But the Bible doesn't say repent and be baptized. Jesus told his apostles to go out into the world baptizing in the name of the Father, and of the Son, and of the Holy Spirit. Nothing about repenting there.
Acts of the Apostles 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Isaiah 30:15 For thus saith the Lord GOD, the Holy One of Israel; In returning and rest shall ye be saved; in quietness and in confidence shall be your strength: and ye would not.
Acts of the Apostles 8:12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.
Matthew 4:17 From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.
Mark 16:15-16 And he said unto them, Go ye into all the world, and preach the gospel to every creature.
He that believeth and is baptized shall be saved; but he that believeth not shall be damned.
Revelation 2:5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
Acts of the Apostles 20:21 Testifying both to the Jews, and also to the Greeks, repentance toward God, and faith toward our Lord Jesus Christ.
Romans 2:4-5 Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?
But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;
1 John 1:8-10 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
If we confess our sins, he is faithful and just to forgive us
our sins, and to cleanse us from all unrighteousness.
If we say that we have not sinned, we make him a liar, and his word is not in us.
I tend to disagree with your statement. The Bible says to repent, tells you how to repent, and encourages it, and shows that if you do not, Christ is not in you.
