Paul did not even preach water baptism when he came to them. He preached the gospel of Jesus Christ, no baptism.
2 Corinthians:
1 And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God.
2 For I determined not to know any thing among you, save Jesus Christ, and him crucified.
So you really think we don't need to get rid of our sins!!
Are you even concerned since you don't reply, did you even search?
How about look at it this way.
This will help you with the gospel that Paul preached TO HIS CHURCH in Corinthian.
He wrote to HIS church in the year 54 or 55 AD.
He asked the Ephesians this in the year 52 to 55 AD.
SAME TIME FRAME.
Acts 19:1 And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
2 He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.
3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
5 When they heard this, they were baptized in the name of the Lord Jesus.
6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
7 And all the men were about twelve.
8 And he went into the synagogue, and spake boldly for the space of three months, disputing and persuading the things concerning the kingdom of God.
9 But when divers were hardened, and believed not, but spake evil of that way before the multitude, he departed from them, and separated the disciples, disputing daily in the school of one Tyrannus.
10 And this continued by the space of two years; so that all they which dwelt in Asia heard the word of the Lord Jesus, both Jews and Greeks.
Since you will not answer if we have to get rid of our sins, how about these questions?
Paul asked these, I ask you.
Have YOU received the Holy Ghost since you have believed?
How were YOU baptized?
Now let's look at verse 10, He stayed there for 2 years teaching who?
If your claiming Paul preached a different gospel you are wrong.
UNLESS, UNLESS Paul preached one message to some and another message to others.
1. Do you think Paul preached different messages?
2. Have YOU received the Holy Ghost since you have believed?
3. How were YOU baptized?
Of course the first question how do we get rid of our sins remains unanswered.
