Paul preached the gospel and many were saved and Paul did not baptize them.
And so many passages declare people were saved with no mention of baptism.
There is only one gospel, Ephesians 4:4-5.
Therefore only one way to be saved, Romans 1:16.
So, people were not saved in diferent ways in the new testament.
If so there are different gospels for different people.
To know the full plan of God saving man you must know the whole sum on any subject.
Summation is how we know Jesus taught how He planned to save us.
For example,
Acts 2:38,
Peter tells them to repent and be baptized.
Did not tell them to believe.
If we cherry pick and ignore the sum. Then we come to the wrong conclusion.
We must find and study every conversion story to get the full picture on how the gospel saves.
Other verses do teach belief.
Acts 16:30-31,
Sirs, what must I do to be saved,
And they said,
believe on the Lord Jesus Christ and thou shalt be saved
We must learn how the Bible teaches.
Failure to learn how the Bible teaches will cause the reader to misunderstand scripture.
One of the things one must learn is the sum, summation.
Another is necessary inference.
Necessary inference is a method of interpreting Scripture where a conclusion is not directly stated.
But it is unavoidable or logically required based on
what IS STATED.
We have Peter command water baptism.
That is stated!!!
That is a Biblical fact.
Then it must be necessarily inferred that Acts 2:38, repentance and baptism are commandments.
Can you be saved without obeying the commandment to repent?
Can you be saved without obeying the commandment to be immersed?
Summation proves when you dont read about belief or repentance or baptism in specific passages related to the conversion of souls.
What has already been said we infer that to where it was not mentioned.
Then you have the full picture of the gospel unto salvation.
So, just because you can find some passage in Acts that doesnt mention baptism that does not mean they weren't baptized.
Likewise with repentance or belief.
Put then all together.
Hear the gospel, Romans 10:17,
Believe the gospel, John 3:16.
Repent, Acts 2:38.
Confess faith in Christ, Romans 10:9-10; Acts 8:37-38.
Baptized into Christ, Acts 2:38 ; Acts 22:16 ; Acts 10:47-48 ; Acts 16:33 ; 1Peter 3:20-21 ; Colossians 2:12 ; Acts 8:12
If we cherry pick verses we will never understand the Bible.
