Is Baptism A Symbol of Dedication?

Let any man who would say that Christian baptism is a symbol of our dedication to God produce one scripture that would substantiate that view. If no scripture can be produced then we have to concede that this view is not Biblical.

That there is no supporting evidence in the Christian Greek scriptures for Christian dedication is evidenced by the "Sing Praises to Jehovah" song book where the two songs concerning Christian dedication (13 & 202) are forced to cite Exodus 39:30 as the song's supporting scripture.

What is Baptism a Symbol of?

Baptism is a symbol of repentance and the means by which we receive forgiveness for our sins.

"Peter [said] to them: “Repent, and let each one of YOU be baptized in the name of Jesus Christ for forgiveness of YOUR sins, and YOU will receive the free gift of the holy spirit." - Acts 2:38

"And now why are you delaying? Rise, get baptized and wash your sins away by your calling upon his name.’" - Acts 22:16

"owing to no works in righteousness that we had performed, but according to his mercy he saved us through the bath that brought us to life and through the making of us new by holy spirit." - Titus 3:5

"That which corresponds to this is also now saving YOU, namely, baptism, (not the putting away of the filth of the flesh, but the request made to God for a good conscience,) through the resurrection of Jesus Christ." - 1 Peter 3:21

If Jesus Was Sinless Why Was He Baptised?

Jesus answers the question himself at Matthew 3:15 "Let it be, this time, for in that way it is suitable for us to carry out all that is righteous"

In order to be sanctified as high priest under the old covenant Aaron had to be cleansed with water and anointed with oil. (Exodus 29:4,7)

Aaron as High Priest was a type for Jesus Christ.

In order to enter into his role as our High Priest Jesus too had to be cleansed with water and anointed with oil. (Hebrews 2:17) Both conditions were fulfilled at the time of his baptism, "After being baptized Jesus immediately came up from the water; and, look! the heavens were opened up, and he saw descending like a dove God's spirit coming upon him." - Matthew 3:16

As firstborn among many brothers Jesus set the example by which we too would be born again as Spiritual sons of God. (Romans 8:29)

In speaking to the Pharisee Nicodemus Jesus described the method by which one would be born again as a son of the Kingdom. "Most truly I say to you, Unless anyone is born from water and spirit, he cannot enter into the kingdom of God. What has been born from the flesh is flesh, and what has been born from the spirit is spirit. Do not marvel because I told you, YOU people must be born again." - John 3:5-7

At the time of his baptism he was born from water and as the Holy Spirit came upon him as a dove he was born from spirit and then the voice called from heaven declaring him, "my Son, the beloved, whom I have approved." (Matthew 3:16,17)
