I have added those words in brackets. Yes we are symbolically buried with Christ in water, and raised again to "walk in newness of life".
But the quotations from Acts 2:38 and Mark 16:16 should not be misunderstood. They need to be properly understood in the light of Gospel truth. BELIEVE ON THE LORD JESUS CHRIST AND THOU SHALT BE SAVED. There is no inclusion of baptism in the matter of salvation.
At the same time, because it is a commandment of Christ, and must follow immediately upon conversion, we read this: And he took them the same hour of the night, and washed their stripes; and was baptized, he and all his, straightway. (Acts 16:33) As you go through the book of Acts you see this happening all the time. But churches today have generally departed from this practice.
I don’t understand how you can say “ there is no inclusion of baptism in the matter of salvation” when Mark 16:16 says “He that believes (belief) and is baptized (baptism) shall be saved.” The conjunction “and” connects things of equal value. Baptism is of the same importance as faith. If I said 1 + 1 = 2, would you have any trouble understanding that? What don’t you understand that belief + baptism = salvation. That is the way Jesus says it. What YOU are saying is 1 (belief) —1 (baptism) = 2 (salvation). Or maybe you are saying 1 (belief = 2 (salvation) —(baptism). Not the same thing is it?
Then Acts 2:38 plainly says that baptism is for the remission of sins. Isn’t that salvation? Why would Peter say that baptism SAVES US if “there is no inclusion of baptism in salvation.” Or why would Ananias tell Paul that he needed to be baptized to “wash away” his sins. And why did Peter COMMAND Cornelius to be baptized? What you are saying does not agree with scripture.
In Acts 16, the jailer was a Roman heathen. Of course the first thing Paul would have told him was he had to believe in Jesus. But he, would likely, have never even heard of Jesus and so, in verse 32, Paul and Silas SPOKE THE WORD OF THE LORD to them— they taught him about Jesus and His gospel. Why do you think they were baptized in the wee hours of the morning? If, like you say, baptism has nothing to do with salvation, Why not wait until a more convenient time? You are correct that all of the New Testament examples of conversion show the converts being baptized immediately, but why was that?? It certainly seems like there would have been at least one example of a believer waiting to be baptized at a later time IF BAPTISM HAS NOTHING TO DO WITH SALVATION. But the fact is that baptism is all about salvation and that accounts for the reason the jailer and his house were baptized IMMEDIATELY in the early morning hours after a stressful and eventful night! And if baptism is not necessary to be saved why did the Ethiopian eunuch in Acts 8 STOP THE CHARIOT?! He was a believer; and if like you believe, he was already saved, then what reason would he have to delay his journey back to Ethiopia any longer by doing something so unnecessay? He could easily wait until he got back home. Besides, how did he even know about baptism? He knew about baptism because “PHILLIP PREACHED JESUS TO HIM.” That is proof that baptism is part of the gospel of Christ. Very much the same as when Paul “SPOKE THE WORD OF THE LORD” to the jailer. They all learned about baptism when they were taught what to do to be saved. And they were ALL baptized immediately—as if it was very important and necessary—which it was.
I hope you are aware that the devil ALWAYS, and I mean ALWAYS tells people the “opposite” of what God says. Go all the way back to the garden of Eden. God told Eve if you eat the fruit, “you will die.” Satan tells her, “No, you will NOT die.” Satan has not changed. God says in the Bible, “ BAPTISM SAVES (1 Peter 3:21). Satan tells people, “No, BAPTISM DOES NOT SAVE.” God says in the Bible, you are NOT (saved) BY FAITH ONLY.”
James 2:24. Satan tells people “Yes, you are SAVED BY FAITH ONLY.” He always says the very opposite of what God says.
1Timothy 4:1 — “Now the Spirit expressly says that in the latter times some will depart from the faith giving heed to deceiving spirits and DOCTRINES OF DEMONS…”
