At Corinth Paul began "solemnly testifying to the Jews that Jesus was the Christ" (Ac 18:5). The angel had said "there has been born for you a Savior, who is Christ the Lord" (Lk 2:11). He was "born for you." Mary was told "'you shall call His name Jesus, for He will save His people from their sins'" (Mt 1:21). Scripture says Jesus is Lord. Jesus confessed, "'You call Me Teacher and Lord; and you are right, for so I am'" (Jn 13:13). Peter stated "that God has made Him both Lord and Christ'" (Ac 2:36). "Every tongue will confess that Jesus Christ is Lord" (Php 2:11). When a person is referred to as a "lord" it means he occupies a supreme place.
When Peter explains Jesus' position he shows "'having been exalted to the right hand of God . . . [he] received from the Father the promise of the Holy Spirit'" (Ac 2:33). Being exalted would be occupying a "supreme place" and he can be referred to as "Lord." To prove it Peter explains that from Jesus' position "'He has poured forth this which you both see and hear'" (:33). This is substantiated because he quotes "'It will come about after this that I will pour out My Spirit on all mankind'" (Joe 2:28). Even Jesus refers to prophecy to make a point. He asks the Pharisees, "'How does David in the Spirit call Him 'Lord,''"(Mt 22:43) for "'if David then calls Him 'Lord,' how is He his son?'" (:45). The reference is "The Lord says to my Lord: 'Sit at My right hand until I make Your enemies a footstool for Your feet'" (Ps 110:1). Jesus was proving that he was the Messiah and "no one was able to answer Him a word" (Mt 22:46).
Part of Jesus' assignment was "to teach and preach in the cities" (Mt 11:1). But he told them, "'My teaching is not Mine, but His who sent Me'" (Jn 7:16). This is not to conclude that he was just a messenger. After the resurrection he declared, "'All authority has been given to Me in heaven and on earth'" (Mt 28:18). "'All things that the Father has are Mine'" (Jn 16:15). Jesus had told them to wait until he sent the Holy Spirit (Lk 24:49) "'whom the Father will send in My name'" (Jn 14:26). Jesus told them "'when He, the Spirit of truth comes, He will guide you into all the truth'" (16:13). All scripture is true. "'He who sent Me is true'" (8:26). Jesus said that the Spirit "'will not speak on His own initiative, but whatever He hears, He will speak'" (16:13). Jesus had said "'the things which I heard from Him, these I speak to the world'" (8:26). He said that the Spirit would "'glorify Me; for He shall take of Mine, and shall disclose it to you'" (16:14). Jesus always gave God credit. When he quoted Exodus 20:12 he said it was the "'commandment of God'" (Mt 15:3) and that "'God said'" (:4) it. When he quoted Exodus 3:6 he said it was "'spoken to you by God'" (22:31). When teaching he asked "'have you not read?'" (19:4) and declared they were "'not understanding the Scriptures'" (22:29). He quoted Deuteronomy 8:3 to prove, "'It is written'" (Lk 4:4) and Isaiah 29:13 to emphasize Isaiah's prophecy (Mk 7:6). He knew that the "Jews ask for signs" (1Co 1:22) so he gave them the "'sign of Jonah the prophet'" (Mt 12:39). He also quoted Psalm 110:1 as an example of an Old Testament anointing where "'David himself said in the Holy Spirit'" (Mk 12:36). This confirms that, "'He will teach you all things, and bring to your remembrance all that I said to you'" (Jn 14:26). "'I did not come to abolish [the Law] but to fulfill'" (Mt 5:17). "'My words will not pass away'" (24:35).
