Matthew 4:17

The form of Christ's message was familiar to the people: From that time Jesus began to preach and to say, Repent; for the kingdom of heaven is at hand.

It had been uttered by John the Baptist in his urgent appeal for a change of heart. But with Jesus it had a greater significance. He must needs preach repentance in order to prepare the way for the proclamation of salvation. He acted, not as a guide to a distant and coming salvation, but as the herald of the kingdom of grace now at hand in Himself. His plea was for a change from the old to the new, from the prophecy and type to the fulfillment. In this way the day-star arose in Christ and His Gospel, and had now begun to shine upon those that were covered with darkness, in order that they might see this light and rejoice in its merciful illumination and warmth.
