MATTHEW 11:2-19, LUKE 7:18-35
Much of the Old Testament deals with future events and the coming Messiah and His Kingdom. Not only was John the Baptist the voice of God to his generation, he was also the fulfillment of Old Testament prophecy. He didn't just prophesy about the coming Messiah and the New Covenant, as the Old Testament prophets did, but he actually prepared the way for the hearts of the people to receive Jesus by bearing witness of Him.
Even though John the Baptist was the greatest of the Old Testament prophets, he was not a born again in Christ. When Jesus was raised from the dead, He enabled us to be "born of the Spirit" and become children of God, heirs of God, and joint-heirs with Jesus.
We were abled to become "partakers of the divine nature" and full-fledged sons of God. John operated under the Old Covenant when none of these promises were yet in effect. Jesus established a new order, "the Kingdom of God," in which these promises became effective. God saw John and all of the Old Testament prophets through the law.
The new birth is necessary for entering the Kingdom of God. Our spiritual man became dead or separated from God through sin. Just as we didn't accomplish our physical birth, we cannot produce spiritual rebirth. We are totally unable to save ourselves; therefore, we need a Savior. We simply believe on the Lord Jesus Christ and we are saved.
Salvation is not a reformation, but rather a regeneration, a new birth, a new creation, that can only be accomplished by a creative miracle of the Holy Spirit. Because of the new birth, He sees us through Jesus. Celebrate Life!
