The Gospel according to Luke includes many details about Jesus’ life that are not included in the other two synoptic gospels, the books that were written by Matthew and Mark. The level of detail that Luke went into about the things that Jesus did help us to link things together and to get a clearer picture of what kind of person Jesus was from a human perspective. One of the events that Luke recorded was an encounter Jesus had with a man named Zacchaeus. Luke tells us that Zacchaeus was a chief tax collector and was rich. Leading up to his story about Zacchaeus, Luke shared other information that was relevant to our understanding of what Jesus was doing when he looked up at Zacchaeus sitting in a sycamore tree and said to him, “Zacchaeus, hurry and come down, for I must stay at your house today” (Luke 19:5).

Luke’s rendition of Jesus’ parable of the persistent widow concluded with Jesus asking the question, “Nevertheless, when the Son of Man comes, will he find faith on the earth?” (Luke 18:8). We don’t know whether Jesus was referring to his first coming or his second coming, but we do know that Jesus found very little faith during his three-year ministry on earth and will likely find even less faith when he comes a second time to interact with fallen humanity. Jesus’ question is an indicator that he was looking for faith when he was here before, and will be looking for it again, when he returns to establish his kingdom on earth. That’s why the situations where Jesus found faith are highlighted in the gospels, and Luke went to even greater lengths to help us see and understand what faith looked like in Jesus’ encounters with the people around him.

Luke stated in his introduction to the parable of the Pharisee and the Tax Collector, that Jesus told this parable “to some who trusted that they were righteous, and treated others with contempt” (Luke 18:9). In this parable, the tax collector is depicted as “standing far off” and Jesus said he “beat his breast, saying, ‘God, be merciful to me, a sinner!’” (Luke 18:13). The tax collector recognized that he was a sinner and knew that he needed God’s mercy. Jesus concluded the parable of the Pharisee and the Tax Collector with the statement, “I tell you, this man went down to his house justified, rather than the other. For everyone who exalts himself will be humbled, but the one who humbles himself will be exalted” (Luke 18:14). The Greek word that is translated justified, dikaioo (dik-ah-yoˊ-o) is “spoken especially of the justification bestowed by God on men through Christ, in which he is said to regard and treat them as righteous, i.e. to absolve from the consequences of sin and admit to the enjoyment of the divine favor” (G1344). It says of justification in Romans 4:4-8:

Now to the one who works, his wages are not counted as a gift but as his due. And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness, just as David also speaks of the blessing of the one to whom God counts righteousness apart from works:

“Blessed are those whose lawless deeds are forgiven,
    and whose sins are covered;
blessed is the man against whom the Lord will not count his sin.”

Paul went on to explain that being justified by faith means that we have access to God’s grace and are saved from the wrath of God, including the wrath of God that will be poured out on all of  mankind during the Great Tribulation (Romans 5:1-11). Paul concluded his discussion of justification with the famous verses of Romans 8:26-30. Paul told the Roman believers, “ Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words. And he who searches hearts knows what is the mind of the Spirit, becausethe Spirit intercedes for the saints according to the will of God. And we know that for those who love God all things work together for good, for those who are called according to his purpose. For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the firstborn among many brothers. And those whom he predestined he also called, and those whom he called he also justified, and those whom he justified he also glorified.”

The tax collector who beat his breast and cried out, “God, be merciful to me a sinner!” (Luke 18:13) openly displayed the kind of repentance that is necessary for justification to take place and also, mirrored the intercession of the Holy Spirit described by Paul as “groanings too deep for words” (Romans 8:26). Luke contrasted this example of genuine belief with that of infants who were being brought to Jesus so that he could bless them (Luke 18:15). The Greek term that Luke used to refer to the children who were being brought to Jesus, brephos (brefˊ-os) is “spoken of a child yet unborn, a fetus (Luke 1:41, 44); usually an infant, babe, suckling (Luke 2:12, 16; 18:15; Acts 7:19; 2 Timothy 3:15). Used metaphorically of those who have just embraced the Christian religion (1 Peter 2:2 [cf. 1 Corinthians 3:2; Hebrews 5:12, 13])” (G1025). Luke tells us, “But Jesus called them to him, saying, ‘Let the children come to me, and do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it’” (Luke 18:16-17).

Luke tells us that when Jesus encountered Zacchaeus, he was sitting in a sycamore tree. Luke said Zacchaeus, “was seeking to see who Jesus was, but on account of the crowd he could not, because he was small in stature. So he ran on ahead and climbed up into a sycamore tree to see him, for he was about to pass by” (Luke 19:2-4). The phrase small in stature refers to Zacchaeus’ “maturity (in years or size)” (G2244). Luke identified Zacchaeus as a man, but he may have just been a male individual who was no longer considered to be a child because he was employed by the Roman government as a tax collector and owned his own residence. Zacchaeus may have been as young as 16 or 17 years old, perhaps the same age as the majority of Jesus’ twelve disciples. The fact that Zacchaeus climbed a tree in order to see Jesus tells that he was either still young enough to do the things that a child would or Zacchaeus was childlike in his approach to overcoming the obstacle of not being able to see Jesus when he passed by.

Luke provided yet another contrast in the stories he shared leading up to Jesus’ encounter with Zacchaeus in the context of a rich ruler who wanted to go to heaven. The rich ruler asked Jesus, “What must I do to inherit eternal life?” (Luke 18:18) suggesting that he was interested in becoming a member of God’s family. The rich ruler told Jesus that he had kept all of God’s commandments from his youth (Luke 18:21), but when the rich ruler heard that he would have to sell all of his possessions and distribute his wealth to the poor in order to enter the kingdom of heaven, “he became very sad, for he was extremely rich” (Luke 18:22). Jesus then, told his disciples, “’How difficult it is for those who have wealth to enter the kingdom of God! For it is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God.’ Those who heard it said, ‘Then who can be saved?’ But he said, ‘What is impossible with man is possible with God’” (Luke 18:24-27). The Greek word that is translated impossible, adunatos (ad-ooˊ-nat-os) is the negative form of the word dunatos (doo-nat-osˊ) which is translated possible, indicating that this couldn’t happen. Jesus was telling his disciples that it was not possible for a rich person to enter the kingdom of God. That’s why they responded, “Then who can be saved?” (Luke 18:26).

Luke’s description of Zacchaeus as a man who was both “a chief tax collector” and “rich” (Luke 19:1) was essentially setting the scene for a miraculous transformation to take place. Luke tells us that after he came down from the sycamore tree, “Zacchaeus stood and said to the Lord, ‘Behold, Lord, the half of my goods I give to the poor. And if I have defrauded anyone of anything, I restore it fourfold.’ (Luke 19:8). Zacchaeus volunteered to do what Jesus told the rich ruler he needed to in order to enter the kingdom of God (Luke 18:22-24). The difference between Zacchaeus and the rich ruler was that Zacchaeus knew who Jesus was and realized that he was having a face to face encounter with God. When Jesus said, “Zacchaeus, hurry and come down, for I must stay at your house today” (Luke 19:5), his words had a big impact on Zacchaeus because they were filled with love and compassion. Everyone likely shunned Zacchaeus because he was helping the Roman government oppress the people of Israel. Luke identified Zacchaeus as a chief tax collector, meaning that he was a person of influence and authority with regard to collecting Roman taxes and had become rich as a result of it. Surprisingly, Jesus’ response to Zacchaeus wasn’t harsh or critical. Jesus said, “Today salvation has come to this house, since he also is a son of Abraham. For the Son of Man came to seek and to save the lost” (Luke 19:9-10). In the Christian sense, salvation or soteria in the Greek, “is deliverance from sin and its spiritual consequences and admission to eternal life with blessedness in the kingdom of Christ” (G4991). Zacchaeus was a sinner, what Jesus described as a person who was lost, but Zacchaeus had an obvious change of heart. Zacchaeus’ encounter with Jesus caused him to repent of his sin and to seek a new way of life. We aren’t told what happened to Zacchaeus after he was saved, but we know that his encounter with God resulted in him doing the impossible, entering into God’s kingdom.
