Jesus told his followers parables about the kingdom of God so that they would be convinced of its existence, even though there was no physical evidence to verify that it was real. When he was asked by the Pharisees when the kingdom of God would come, Jesus answered them, “The kingdom of God is not coming in ways that can be observed, nor will they say, ‘Look, here it is!’ or “There!’ for behold the kingdom of God is in the midst of you” (Luke 17:20-21). The Greek word that is translated in the midst, entos (en-tosˊ) means “inside” (G1787). One of the primary parables that Jesus used to explain the internal workings of God’s kingdom was the parable of the sower. Jesus said, “A sower went out to sow his seed. And as he sowed, some fell along the path and was trampled underfoot, and the birds of the air devoured it. And some fell on the rock, and as it grew up, it withered away, because it had no moisture. And some fell among thorns, and the thorns grew up with it and choked it. And some fell into good soil and grew and yielded a hundredfold” (Luke 8:5-8). When Jesus’ disciples asked him what the parable meant, Jesus told them, “To you has been given to know the secrets of the kingdom of God, but for others they are in parables, so that seeing they may not see, and hearing they may not understand. Now the parable is this: The seed is the word of God. The ones along the path are those who have heard; then the devil comes and takes away the word from their hearts, so they may not believe and be saved” (Luke 8:10-12).

Jesus identified the seed in his parable of the sower as the word of God and said that its intended location was people’s hearts, where it would enable them to believe and be saved. From this we can conclude that the kingdom of God being inside us has to do with God ruling and reigning over people’s hearts. The heart is “the seat and center of circulation, and therefore human life” In the New Testament of the Bible, the term heart is used only figuratively: “As the seat of desires, feelings, affections, passions, impulses, i.e. the heart or mind” (G2588). Jesus described the things that come out of our hearts as fruit and said, “Either make the tree good and its fruit good, or make the tree bad and its fruit bad, for the tree is known by its fruit” (Matthew 13:33). Paul talked about circumcision of the heart in his letter to the Romans and said, “For no one is a Jew who is merely one outwardly, not is circumcision outward and physical. But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter” (Romans 2:28-29). Paul went on to explain that circumcision was a seal of righteousness that was first received by Abraham as a sign of his faith in God. Paul said, “The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well, and to make him the father of the circumcised who are not merely circumcised but who walk in the footsteps of the faith that our father Abraham had before he was circumcised” (Romans 4:11-12).

Walking in the footsteps of faith means that we are responding to the promptings of the Holy Spirit. Grace is defined as “the divine influence upon the heart, and its reflection in the life” (G5485). Paul indicated in his letter to the Galatians that the fruit of the Spirit, which the reflection in the life of the divine influence upon the heart, is the result of believers crucifying their flesh with its passions and desires. Paul said:

But I say, walk by the Spirit, and you will not gratify the desires of the flesh. For the desires of the flesh are against the Spirit, and the desires of the Spirit are against the flesh, for these are opposed to each other, to keep you from doing the things you want to do. But if you are led by the Spirit, you are not under the law. Now the works of the flesh are evident: sexual immorality, impurity, sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God. But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. And those who belong to Christ Jesus have crucified the flesh with its passions and desires.

If we live by the Spirit, let us also keep in step with the Spirit. Let us not become conceited, provoking one another, envying one another.

Paul contrasted the works of the flesh with the fruit of the Spirit so that it would be clear to us what God’s kingdom on earth should look like. The fruit of the Spirit is not something that can be seen, but it is a physical manifestation of what is taking place in our hearts and therefore, evidence of the existence of God’s kingdom inside of us. When the divine influence upon the heart is reflected in the life of believers, it is obvious because it is very different from what we typically see in the world around us.

The closer we get to the time of Jesus Christ’s return, the more difficult it will be to see any evidence of God’s divine influence upon people’s hearts. Jesus said, “Just as it was in the days of Noah, so will it be in the days of the Son of Man. They were eating and drinking and marrying and being given in marriage, until the day when Noah entered the ark, and the flood came and destroyed them all. Likewise, just as it was in the days of Lot—they were eating and drinking, buying and selling, planting and building, but on the day when Lot went out from Sodom, fire and sulfur rained from heaven and destroyed them all—so will it be on the day when the Son of Man is revealed” (Luke 17:26-30). Christ’s sudden appearing from heaven will be an unexpected shock to most people. Jesus said, “For as the lightning flashes and lights up the sky from one side to the other, so will the Son of Man be in his day” (Luke 17:24). Jesus’ return will be like a bolt of lightning that jolts everyone into a keen awareness of the immediate danger. As noted in the parable of the ten virgins (Matthew 25:1-13), there will be no time for believers to refresh their supply of the anointing of the Holy Spirit when the announcement of Christ’s arrival goes out.

We are told in the book of Revelation that the internal kingdom of God will eventually become an external kingdom that will encompass both heaven and earth (Revelation 12:10). The resurrection of the dead is a key element in the transition from an internal kingdom to an external kingdom that is ruled by Jesus Christ. Paul said, “But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep. For as by a man came death, by a man has come also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive. But each in his own order: Christ the firstfruits, then at his coming those who belong to Christ. Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power. For he must reign until he has put all his enemies under his feet. The last enemy to be destroyed is death. For God has put all things in subjection under his feet” (1 Corinthians 15:20-27). The end that Paul was speaking of, when Christ delivers the kingdom to God the Father, is not an ending in the sense that there is nothing afterwards. The Greek word telos (telˊ-os) refers to “the conclusion of an act or state.” It is “a noun meaning an end, a term, a termination, completion. Particularly only in respect to time” (G5056). Paul went on to explain, “For this perishable body must put on the imperishable, and this mortal body must put on immortality. When the perishable puts on the imperishable, and the mortal puts on immortality, then shall come to pass the saying that is written: ‘Death is swallowed up in victory’” (1 Corinthians 15:53-54).

Immortality is the opposite of death, the extinction of life (G110). In order for us to be able to participate in the eternal kingdom of God, Paul said our perishable body must put on the imperishable, and our mortal body must put on immortality (1 Corinthians 15:53). Paul used similar language in his letter to the Ephesians where he instructed believers to “put off your old self which belongs to your former manner of life and is corrupt through deceitful desires, and to be renewed in the spirit of your minds, and to put on the new self, created after the likeness God in true righteousness and holiness” (Ephesians 4:22-24). The Greek word that is translated corrupt, phtheiro (fthiˊ-ro) means to corrupt in the sense of “to make depraved” (G5351), in other words, to be in a state of moral depravity, exhibiting perversion as shown by a capacity for extreme and wanton physical cruelty. Paul said believers need to put off their old selves (heart desires) because they belong to our former manner of life and are corrupt through deceitful desires (Ephesians 4:22). The only way this can be done is “to be renewed in the spirit of your minds” (Ephesians 4:23). The Greek word that is translated renewed, ananeoo (an-an-neh-oˊ) means “to renovate, i.e. reform” (G365). The internal workings of believers’ hearts have to undergo a transformative change, going from a corrupted way of thinking to a godly way of thinking and behaving.

Jesus warned his disciples to not be concerned about their physical possessions when they become aware of his imminent return. Jesus said, “’On that day, let the one who is on the housetop, with his goods in the house, not come down to take them away, and likewise let the one who is in the field not turn back. Remember Lot’s wife. Whoever seeks to preserve his life will lose it, but whoever loses his life will keep it. I tell you, in that night there will be two in one bed. One will be taken and the other left. There will be two women grinding together. One will be taken and the other left.’ And they said to him, ‘Where, Lord?’ He said to them, ‘Where the corpse is, there the vultures will gather’” (Luke 17:31-37). The disciples’ question, “Where, Lord?” had to do with their misunderstanding of the internal nature of God’s present kingdom. Jesus’ disciples did not believe that the kingdom of God could exist on earth unless it was in a physical form. Jesus’ response was a reference to the apostate church that will be present on the earth at his second coming. At that time, the physical churches that most people think are filled will born again Christians will actually be filled with unbelievers. There will be no evidence of divine influence upon those people’s hearts. The body of Christ will be perceived to be a corpse that has been overtaken by satanic influence, as evidenced by the corrupt behavior of all its members. The actual body of Christ, true believers, will still be present on the earth when Christ returns, they are the ones that will be taken, raptured in that night (Luke 17:34-35; 1 Thessalonians 4:14-5:11).
