Each of the Gospel writers chose a different starting point for their accounts of the life of Jesus. In the beginning of his gospel account, John presents the largest perspective of all, describing Jesus as the very source of everything we understand as beginning. The first 18 verses are so epic and grand about who Jesus is and all he came to do. The Apostle John wrote his Gospel to help his readers understand the identity and deity of Jesus. Jesus is way MORE than you think and John writes to persuade you, so that you may BELIEVE.
