Throughout His earthly ministry, Jesus was preaching “repent and believe” (Mk 1:15, Mk 1:38) and teaching his disciples to go out and preach repentance (Mk 1:17, Mk 6:12, etc.), first. The miracles and all of His divine dealings were a springboard for His message of salvation.
1) Showed the divinity of Jesus. “Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the miracles themselves” (John 14:11). Which, in return…
2) Provided Him an audience to hear His message of repent and believe. Crowds came to see Jesus drawn by the prospect of seeing or receiving a miracle – what they received was far greater.
3) Showed compassion – Throughout the New Testament we see His compassion. Example: “When Jesus landed and saw a large crowd, He had compassion on them and healed their sick (Matthew 14:14). We must have compassion to minister to the lost. Compassion is a byproduct of love, and love is the fuel for the believer to reach out to a hurting and lost world.
Ultimately, everything that was written about Jesus and everything He did led to the cross. At the end of the Gospel of Luke, Jesus speaks perfectly concerning what has transpired:
Luke 24:44-47, “Now He said to them, “These are My words which I spoke to you while I was still with you, that all things which are written about Me in the Law of Moses and the Prophets and the Psalms must be fulfilled.” Then He opened their minds to understand the Scriptures, and He said to them, “Thus it is written, that the Christ would suffer and rise again from the dead the third day, and that repentance for forgiveness of sins would be proclaimed in His name to all the nations, beginning from Jerusalem.”
