The Lord Jesus came to this earth to proclaim salvation to man, declaring the glory and mission of the Almighty (John 1:18). As He walked on this earth, it was His mission to teach the way of righteousness to those in bondage to sin. The Scriptures teach that all have sinned and come short of the glory of God (Romans 3:23). The consequence of this “falling short” is death, spiritual death (Romans 6:23). Since man has fallen short of God’s salvation, the only “bridge” to the Father is via Jesus. He is the way, the truth and the life (John 14:6).
The mission and the message of Jesus was not readily received, however. He came unto those that were similar to Him with a message of God, but a great many were not interested in what He had to say; that is, they were intrigued, but not converted (cf. John 1:5-10). Though some responded that way, not all did. One such person was a great teacher among the rabbis; his name was Nicodemus. He came to the Lord Jesus in the night time hours, declaring to Him that no man can do the things He (Jesus) had done, unless God is with him (John 3:2). Nicodemus heard the words of the Lord, but it was the miraculous confirmation/authentication of that word spoken that said to him this man is from God.
Clearly, the authenticating signs (miraculous works) Jesus did was to convince people that what He spoke was not of human origin. “Now while Jesus was in Jerusalem at the feast of the Passover, many people believed in his name because they saw the miraculous signs he was doing” (John 2:23, NET). Jesus did not do this for Himself, or simply to bring attention to Himself as a man preaching; He did this for the sole purpose of “declaring God” (1:18).
The Gospel (or Book) of John is a good place to see why Jesus made use of the miraculous signs. It was not His intent to bring attention to Himself as a man, but to bring attention to Himself in the message He preached. There is a difference (John 5:30). Thus, slowly, prayerfully and with desire to please God, please read the Gospel of John.
