John the Baptist came as the forerunner, but he himself was not the true light. He only came as a witness to the Coming One, the Messiah. The prophet Isaiah foretold of this coming light in Isaiah 49:6, “I will make You as a light for the nations, that My salvation may reach to the end of the earth.” Jesus Christ came to shine the light of His truth into the darkness for all men…this is called Common Grace which expresses the goodness of God to all. God graciously blesses all men with undeserved things such as rain, sun, health, and happiness…but common grace stops short of saving grace…which all human beings need… the saving work of the Holy Spirit to reconcile themselves to God.
