Jesus Christ is the Lord. Acts 2:38 is the keys to the kingdom of God. Our foundation is built upon that of the apostles and prophets, Jesus Christ as the chief cornerstone.
As long as we understand what that Scripture is actually saying.
38) Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
The person being baptized is doing so because their sins were forgiven when they asked Jesus into their lives as Lord and Savior. The water baptism spoken of is not done so that ones sins may be forgiven.
Simple way to understand:
Are they being baptized to have sins forgiven
Are they being baptized because their sins were forgiven
Put it this way:
Repent and jump for joy for the forgiveness of sin.......
The late Adrien Rogers first made this comparison to reveal that water baptism did not cleanse one of sin. Only the precious blood of Jesus can do that. Water baptism is the first act of obedience! We are water baptized because Jesus said we should be. Water baptism serves as a witness to the world and the Church that a person has become a believer in and follower of Jesus Christ.
The baptism of the Holy Spirit is the baptism that cleanses people of their sins, for this is how the precious blood of Jesus is applied. However, the Holy Spirit baptism cannot be seen by the eye. Thus, water baptism serves as a symbol that can be seen, just as when Jesus was baptized by John the Baptist.
The "keys" to the kingdom of God is the precious blood of Jesus, not water baptism IMO.
