The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world. This is he of whom I said, After me cometh a man which is preferred before me: for he was before me. And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water. John 1:29-31
As soon as John the Baptist saw Jesus he declared “Behold the Lamb of God who takes away the sin of the world” Now for the Gentiles this wouldn’t make any sense, but John was declaring this to the Jewish people, who knew he was referencing the Passover Lamb of Exodus. Jesus is the ultimate sacrifice to pay the wages for our sin
Revealed earlier, John the Baptist is the Messenger in the Wilderness prophesied by Isaiah, to prepare the way for The Lord. How did he prepare them? He preached a message of repentance and baptized them with water to make a profession of their faith.
And John bare record, saying, I saw the Spirit descending from heaven like a dove, and it abode upon him. And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost. And I saw, and bare record that this is the Son of God. John 1:32-34
John witnessed the Holy Spirit descending from Heaven and anointed Jesus as the Messiah. Why would the Son of God need to be filled with the Holy Spirit? Well remember Jesus became flesh to be the Lamb of God, Jesus is fully God and fully human , a concept that is difficult for our minds to grasp (Philippians 2)
Notice John baptizes with water, but Jesus baptizes with the Holy Spirit. Nobody else can baptize with the Holy Spirit except Christ alone. John the Baptist not only declared these things as a prophet but he was a witness to all these things!
When you feel there is no hope in this world, remember The Lamb of God took away the sin of the world so that we may be reconciled back to The Father Amen!
