When someone asks, “Do what?”, Jesus already answered this clearly by His own words and by how He dealt with people.
Jesus said, “Repent ye, and believe the gospel” (Mark 1:15). He also said, “Follow me” (Matthew 4:19). Following Him was never just words. It meant listening to Him and doing what He taught. Jesus said, “If ye love me, keep my commandments” (John 14:15), and again, “Whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man” (Matthew 7:24). Love for God was shown by obedience, not by claims.
This is made very clear in the story of the rich young ruler. A man came to Jesus and asked, “Good Master, what shall I do that I may have eternal life?” (Matthew 19:16). Jesus did not say, “Nothing.” Instead, He answered, “If thou wilt enter into life, keep the commandments” (Matthew 19:17). Jesus then named commandments about not killing, not stealing, not lying, honoring parents, and loving your neighbor. These were real actions in daily life. The man said he had kept them, but Jesus looked deeper into his heart. Jesus said, “If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven and come and follow me” (Matthew 19:21).
Jesus was not teaching here that money itself was evil. He was showing that this man loved his possessions more than God. The command showed what ruled his heart. The man went away sorrowful because he would not obey. This shows that believing in Jesus without following Him is not enough. Jesus asked for a heart that puts God first and shows love through action.
Jesus also taught that love is lived out in simple deeds. He said, “Thou shalt love the Lord thy God with all thy heart” and “Thou shalt love thy neighbour as thyself” (Matthew 22:37–39). He said, “Give to him that asketh thee” (Matthew 5:42), and “Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me” (Matthew 25:40). Feeding the hungry, helping the weak, and showing mercy were never optional. They were part of following Him.
So when Jesus told people what to do, He was clear. Repent. Believe. Follow Him. Keep His commandments. Love God above all. Love others in real ways. Hear His words and do them. This is what Jesus Himself taught, and this is the path He called people to walk.
