One of the primary obstacles that Jesus faced in his mission to save the world was the unbelief of the people of Israel. Mark’s gospel tells us when Jesus came to his hometown, they “took offense at him” (Mark 6:3). The Greek word that is translated offense, skandalizo (skan-dal-idˊ-zo) means to “scandalize.” In a moral sense, skandalizo means “to be a stumbling block to someone, to cause to stumble at or in something, to give a cause of offence to someone. It says in Mark 6:1-6:

He went away from there and came to his hometown, and his disciples followed him. And on the Sabbath he began to teach in the synagogue, and many who heard him were astonished, saying, “Where did this man get these things? What is the wisdom given to him? How are such mighty works done by his hands? Is not this the carpenter, the son of Mary and brother of James and Joses and Judas and Simon? And are not his sisters here with us?” And they took offense at him. And Jesus said to them, “A prophet is not without honor, except in his hometown and among his relatives and in his own household.” And he could do no mighty work there, except that he laid his hands on a few sick people and healed them. And he marveled because of their unbelief.

Jesus’ family, friends, and neighbors saw him as an ordinary man. Rather than accepting him as their Messiah, the Son of God, the people in his hometown associated Jesus with his occupation, and referred to him as “the carpenter” (Mark 6:3). Mark said that Jesus could do no mighty work or miracles there because of their unbelief.

Unbelief is the state a person is in before embracing the gospel, but it can also be a violation of faith or apostasy (G570). The writer of Hebrews admonished the people of Israel because of their unbelief. Hebrews 3:12-19 states:

Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end. As it is said,

“Today, if you hear his voice,
do not harden your hearts as in the rebellion.”

For who were those who heard and yet rebelled? Was it not all those who left Egypt led by Moses? And with whom was he provoked for forty years? Was it not with those who sinned, whose bodies fell in the wilderness? And to whom did he swear that they would not enter his rest, but to those who were disobedient? So we see that they were unable to enter because of unbelief.

The writer of Hebrews associated unbelief with the heart, and also indicated that a person could become hardened by the deceitfulness of sin.

In his parable of the sower, Jesus identified different locations that the seed could end up after it was sown and explained to his disciples that the seed represented the word of the kingdom or the gospel. Jesus said, “When anyone hears the word of the kingdom and does not understand it, the evil one comes and snatches away what has been sown in his heart” (Matthew 13:19). According to Jesus the intended destination for the gospel is the heart, but Satan tries to keep us from understanding God’s word so that it doesn’t have any effect on us. Jesus went on to explain that the seeds that fell on rocky ground are, “the ones who, when they hear the word, immediately receive it with joy. And they have no root in themselves, but endure for a while; then when tribulation or persecution arises on account of the word, immediately they fall away” (Mark 4:16-17). The seeds that fell on rocky ground may have been a direct reference to Jesus’ twelve disciples, who were noted by Mark as abandoning Jesus in the Garden of Gethsemane. Mark said, “They all left him and fled” (Mark 14:50). After Jesus fed five thousand people with five loaves of bread and two fish, he came to his disciples in the middle of the night walking on the sea. Mark tells us, “And he got into the boat with them, and the wind ceased. And they were utterly astounded, for they did not understand about the loaves, but their hearts were hardened” (Mark 6:51-52).

The reason why Jesus’ disciples were utterly astounded when he walked across the water and got into the boat with them was because there was no logical explanation for what had just happened, they may have even thought they were losing their minds or were hallucinating. Mark says, “When they saw him walking on the sea they thought it was a ghost” (Mark 6:49). Mark’s assessment of the situation was linked to what had happened the day before. Mark said, “They did not understand about the loaves” (Mark 6:52). The Greek word that is translated understand, suniemi (soon-eeˊ-ay-mee) means “to bring together in the mind, to grasp concepts and see the proper relation between them. Hence, to comprehend, understand, perceive” (G4920). At this point in the disciples’ relationship with Jesus, it is likely that they were grappling with the fact that God had become a man, that the man they knew as Jesus, was actually God. In one of Jesus’ final conversations with his disciples, John lets us know that his disciples still couldn’t completely comprehend how Jesus, a man, could also be God. John writes:

Philip said to him, “Lord, show us the Father, and it is enough for us.” Jesus said to him, “Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, ‘Show us the Father’? Do you not believe that I am in the Father and the Father is in me? The words that I say to you I do not speak on my own authority, but the Father who dwells in me does his works. Believe me that I am in the Father and the Father is in me, or else believe on account of the works themselves. John 14:8-11)

Jesus told Philip that the Father dwelt in him, that he was in the Father and the Father was in him. Jesus was speaking “of the relation in which one person or thing stands with another…thus to remain in or with someone, i.e. to be and remain united with him, one with him in heart, mind, and will” (G3306). Jesus concluded his conversation with Philip with the statement, “Believe me that I am in the Father and the Father is in me, or else believe on account of the works” (John 14:11). Believing means that you have faith in someone or something. “Particularly, to be firmly persuaded as to something…with the idea of hope and certain expectation (Acts 18:8)” (G4100). The Greek word pisteuo (pist-yooˊ-o), which is translated believe, is derived from the word pistis (pisˊ-tis), which speaks “(of religious truth, or the truthfulness of God or the religious teacher), especially reliance upon Christ for salvation” (G4102).

Jesus’ miracle of feeding five thousand people with five loaves and two fish was motivated by compassion. Mark tells us about Jesus, “When he went ashore he saw a great crowd, and he had compassion on them, because they were like sheep without a shepherd. And he began to teach them many things” (Mark 6:34). The Greek word that Mark used that is translated shepherd, poimen (poy-maneˊ) is translated pastors in the King James Version of Ephesians 4:11 where Paul talks about the various manifestations of grace in the context of unity in the body of Christ. Paul said, “And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, to equip the saints for the work of ministry, for building up the body of Christ, until we all attain the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, but craftiness in deceitful schemes. Rather, speaking the truth in love, we are to grow up in every way unto him who is the head, into Christ, from whom the whole body, joined and held together by every joint with which it is equipped, when each part is working properly, makes the body grow so that it builds itself up in love” (Ephesians 4:11-16). Paul identified the goal of Christianity to be attaining the unity of faith and of the knowledge of the Son of God. The role of the pastor or shepherd in this endeavor is to act as a spiritual guide for believers whose faith is being developed as they grow in their knowledge of the Son of God.

Paul said in his letter to the Romans that the Israelites were like branches that had been broken off because of their unbelief, and then added, “But you stand fast through faith (pistis)” (Romans 11:20). Standing fast implies that there is a force that is trying to move you or perhaps, knock you down. The Greek word histemi (hisˊ-tay-mee), which is translated stand fast, is used metaphorically in Acts 7:60 as “to impute, e.g. sin unto someone” (G2476). Histemi is used three times in Ephesians 6:11-14 where Paul talks about putting on “the whole armor of God that you may be able to stand against the schemes of the devil” (Ephesians 6:11). Paul concluded his discussion of spiritual warfare with the statement, “In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one, and take the helmet of salvation, and the sword of the Spirit, which is the word of God, praying at all times in the Spirit, with all prayer and supplication” (Ephesians 6:16-18). Paul indicated that we must take up the shield of faith, suggesting that faith involves an intentional effort on our part to protect ourselves from spiritual attacks. Paul said that we can not only use our faith to protect ourselves from the enemy’s attacks, but we can also use our faith to launch a counter attack by praying in the Spirit at all times. From that standpoint, it could be said that prayer is a weapon that believers have at their disposal to overcome their unbelief.
