Consider the message and the pattern in the book of Acts:
This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear. For David is not ascended into the heavens but he saith himself,"
"The Lord said unto my Lord, Sit thou on my right hand, until I make thy foes thy footstool."
Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ."(Acts 2:31-36)
This is the same message that is preached by Peter and John at the Temple:
But those things, which God before had shewed by the mouth of all his prophets, that Christ should suffer, he hath so fulfilled. Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began. (Acts 3:18-21)
Notice that the message of the prophets is emphasised as well as the 'refreshing'. There are two key elements here that run throughout the New Testament, hearing the Gospel and receiving the Holy Spirit.
To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins. While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost. (Acts 10:31,32)
With that in mind consider this, there were those who were baptised and yet did not receive the Holy Spirit. The disciples of John at Ephesus and the Samaritans.
"Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John, Who, when they were come down, prayed for them, that they might receive the Holy Ghost (For as yet he was fallen upon none of them only they were baptized in the name of the Lord Jesus.) Then laid they their hands on them, and they received the Holy Ghost. And when Simon saw that through laying on of the apostles' hands the Holy Ghost was given, he offered them money, Saying, Give me also this power, that on whomsoever I lay hands, he may receive the Holy Ghost" (Acts 8:14-18)
Baptism is identified with repentance but salvation is identified by the indwelling of the Holy Spirit. I believe you should be baptised just like I think you should be buried when you die. You would be just as dead if you were not buried and the same thing is true of the death of the old man.
For he that is dead is freed from sin. Now if we be dead with Christ, we believe that we shall also live with him: Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him. For in that he died, he died unto sin once: but in that he liveth, he liveth unto God. Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord. (Acts 6:7-11)
Isn't it odd that the commandment in the Old Testament to do no work on the Sabbath became a part of a works righteousness? Do you think that it is conceivable that we sometimes turn baptism into a kind of a work when we make it a requirement for salvation.
Don't get me wrong, I know how important baptism is and would never diminish this sacred ceremony. I was baptised as an infant, baptised later in the name of the Father, Son and Holy Spirit and again later baptised in Jesus name. You know what, I am even circumcised so I am completely confident that I have been sufficiently ceremonialized. None of this should convince me or anyone else that I am indeed 'In Christ', only the indwelling of the Holy Spirit can assure us of that.
I don't mean to preach and I certainly don't want to get involved in some divisive or contentious debate on water salvation. I'm just saying, despite it's wonderful significance you are justified by faith not by even our most sacred rites.
Grace and peace,
Mark
