Gospel of John Connections :-

The gospel of John’s portrayal of Jesus as the God of the Old Testament is seen most emphatically in the seven “I Am” statements of Jesus. He is the “Bread of life” (John 6:35), provided by God to feed the souls of His people, just as He provided manna from heaven to feed the Israelites in the wilderness (Exodus 16:11–36). Jesus is the “Light of the world” (John 8:12), the same Light that God promised to His people in the Old Testament (Isaiah 30:26; 60:19–22) and which will find its culmination in the New Jerusalem when Christ the Lamb will be its Light (Revelation 21:23). Two of the “I Am” statements refer to Jesus as both the “Good Shepherd” and the “Door of the sheep.” Here are clear references to Jesus as the God of the Old Testament, the Shepherd of Israel (Psalm 23:1; 80:1; Jeremiah 31:10; Ezekiel 34:23) and, as the only Door into the sheepfold, the only way of salvation.
The Jews believed in the resurrection and, in fact, used the doctrine to try to trick Jesus into making statements they could use against Him. But His statement at the tomb of Lazarus, “I am the resurrection and the life” (John 11:25), must have astounded them. He was claiming to be the cause of resurrection and in possession of the power of life and death. None other than God Himself could claim such a thing. Similarly, Jesus’ claim to be “the way, the truth and the life” (John 14:6) linked Him unmistakably to the Old Testament. His is the “Way of Holiness” prophesied in Isaiah 35:8; He established the City of Truth of Zechariah 8:3 when He was in Jerusalem and preached the truths of the gospel. As “the Life,” Jesus affirms His deity, the Creator of life, God incarnate (John 1:1–3; Genesis 2:7). Finally, as the “true Vine” (John 15:1, 5), Jesus identifies Himself with the nation of Israel, who are called the vineyard of the Lord in many Old Testament passages. As the true Vine of the vineyard of Israel, He portrays Himself as the Lord of the “true Israel”—all those who would come to Him in faith (cf. Romans 9:6).
