In the New International Commentary on the New Testament, William Lane describes Jesus' message at the start of his ministry as a call "to radical decision." Mark 1:14-15 shows Jesus preaching in effect that the time is now, the sovereign authority of God is near, have a radical change of heart and mind and believe the good news. The description of the kingdom being near is not completely clear. We do learn later that Jesus is the door and the king of that wonderful kingdom. Throughout his ministry Jesus constantly confronted people with the nature of a kingdom decision. It was a life-altering vote between this world with its empty promises and vain pursuits and the next with its promise of an exciting eternal life. Let us too make a radical decision because the sovereign authority of God is near.
