God has always raised up leaders in times of need. The greatest need of man (lost because of sin) required the coming of Jesus, but to prepare the way for Jesus, God raised up John the Baptist. Luke 1:16,17 states, "And he will turn many of the sons of Israel back to the Lord their God. It is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous, so as to make ready a people prepared for the Lord."
John himself said, "I am a voice of one crying in the wilderness, 'Make straight the way of the Lord,' as Isaiah the prophet said."
Come see how John led others to Jesus and how Jesus leads us to the Father.
