Jesus made three direct statements about His mission on earth (which was God’s mission13). First, He said He came to “seek and to save the lost”3. This is possibly the most well-known fact about His mission. He was the remedy for sin12,15, culminating in His death, burial, and resurrection10. The salvation aspect of His mission is repeated and reiterated several times in Scripture in various ways2,5,6, including Jesus’ own analogy of Himself to a door and a shepherd11.
Second, Jesus said that He came to “bear witness to the truth”1. Specifically, He ushered in the gospel of the kingdom of God9. The words He spoke were from the Father (John 17:14-17) which He embodied12 by becoming flesh (John 1:1,14). This is highlighted when Jesus says He came not to bring peace but a sword4 and when Paul says the Old Law was nailed to the cross7. It was a fulfilling all that had been communicated by God to that point14 and freeing us from fleshly sin to live in/with His Spirit12.
Third, Jesus said He came “for judgment”8…which links to the first two. Jesus came to judge all mankind8 against the truth1,9 of God’s word. Those that accept/believe Him (e.g. enter through “the door”11) receive eternal salvation2,3,8,10.
