Presumably at daybreak, Jesus is trying to find a deserted place. But people — actually crowds — “are searching for Him. They come to Him and try to keep Him from leaving them.” These crowds want Him to remain with them, at their beck and call, at their command. And, it is not as if Jesus does not love them or want to meet their needs. Rather, He says to them, “I must proclaim the good news about the kingdom of God to the other towns also, because I am sent for this purpose.” (Luke 4:43)
The night before, Jesus rebukes demons that shout out His true identity. He commands them not to speak “because they know He is the Messiah.” (Luke 4:41) So, on the one hand, Jesus proclaims “the kingdom of God is near” while on the other hand He silences those who know He is “the Son of God!” (Luke 4:41)
Jesus preaches of loving God above all, of having faith, of avoiding sin, of forgiving enemies, of setting aside self, of giving, of acceptance of others, of freedom from worry and oppression, of God’s favor. Simultaneously, Jesus forgives and heals. Jesus does not preach of Himself; rather He points people to the kingdom of God. He proclaims, “Worship the Lord your God, and serve Him only.” (Luke 4:8) And, He reminds, “Seek first the kingdom of God and His righteousness, and all things are provided for you.” (Matthew 6:33)
Jesus preaches the Word of God to the crowds pressing in to hear. Later, with a huge catch of fish amazing Simon Peter so that he falls at the Lord’s feet, Jesus tells him, “Don’t be afraid. From now on you will be catching people!” (Luke 5:10)
Jesus catches people for the kingdom of God. For this purpose, He comes to earth.
