The eighth “I am” statement is a series of statements throughout the Gospel of John (4:26; 8:24, 28, 58; 13:13, 19; 3:14; 18:5-6, 8). These “I am” statements are also of crucial importance, since “I am” is the Old Testament name of God (cf. Ex. 3:14-15; frequently in Is. 40-66: e.g., 41:4; 43:10-13, 25; 45:18; 51:12; 52:6). The use of “I am” statements involves a divine self-reference on the part of Jesus. By using “I am” Jesus is identifying Himself as Yahweh.
John recorded Jesus using an emphatic “I am” to bring out important teachings about His person; that He is God. In this series is posts, we looked at the two groups of “I am” statements; one group Jesus adds a predicate to His “I am” (i.e. “I am the Good Shepherd”), while in the other group, the “I am” stands by itself. The main purpose for the Gospel of John is to show Jesus to be God. John records eight signs that point to Jesus’ divine power. John gives us several witnesses: John the Baptist; the Samaritan woman; Moses; the Father; Jesus himself, including His works; the Holy Spirit; the disciples; and the Apostle John himself. John also gave the eight “I am” statements. All these support the notion that Jesus is in fact the Messiah and the Son of God.
