Belief

John 2:11,22,23
This beginning of signs Jesus did in Cana of Galilee, and manifested His glory; and His disciples believed in Him.
Therefore, when He had risen from the dead, His disciples remembered that He had said this to them; and they believed the Scripture and the word which Jesus had said.
Now when He was in Jerusalem at the Passover, during the feast, many believed in His name when they saw the signs which He did.

John uses the word "believe" (Pisteuo in the Greek) or a form of it 86 times in his gospel. It is used 19 times in just the first four chapters! John 2 gives three tangible examples of how belief comes about. In verse 11 the disciples believe based on his WONDERS. He reveals His glory to them through His nature and person. Over 7 days or so Jesus' identity oozes out and their friendship is turned to faith. Later, in verse 22, the disciples believe based on the WORD of God. They recall the Old Testament prophesies and realize that Jesus is the fulfillment of these. Finally, the crowds in Jerusalem believed based on His WORKS and the man miracles of healing and life-change He performed.
The lesson here is that there are many paths of faith but all paths must converge in belief in Jesus Christ. He is the only doorway to salvation (John 1:7 & 12).

Jesus, thank You for revealing Yourself through Your wonders, Your Word and Your works. Deepen my faith and strengthen my belief in You. Help me reveal Your nature to others that they too may beleive in You. Amen.
