There are many who teach we do not have to repent. They teach repent means to change your mind about God. What error they teach.
Acts 3:19 Therefore repent and turn back so that your sins may be wiped out,
That scripture says to REPENT AND TURN BACK.
But you steadfastly refuse to believe that your sins are wiped out
Acts 17:30 Therefore, although God has overlooked such times of ignorance, he now commands all people everywhere to repent,
That scripture plainly and clearly is about REPENTING FROM SIN.
If you have repented and your sins are wiped out why are you still fussing with them....have done with them, the matter is settled
Revelation 3:19 Those whom I love I rebuke and discipline. So be earnest and repent.
We see Christ often rebuking Peter and discipling him.
Revelation 3:3 Remember, therefore, what you have received and heard; obey it,
What you [should have] recieved was believe on the Lord Jesus Christ and you SHALL BE saved....get this settled first then....
and repent. But if you do not wake up, I will come like a thief, and you will not know at what time I will come to you.
.....This will also be settled
Revelation 2:5 Consider how far you have fallen! Repent and do the things you did at first.
What you did at first was you BELIEVED on Him, your heart overflowed with love and joy...you would do ANYTHING for Him....now it has all become a weary drudge hasn't it...how can you have fallen so far?
If you do not repent, I will come to you and remove your lampstand from its place.
Those scriptures are about repenting even after being saved.
Keep turning back to your first experience if you had it...you believed and you were saved and filled with gladness
2 Corinthians 12:21 I am afraid that when I come again, my God may humiliate me before you, and I will grieve for many of those who previously sinned and have not repented of the impurity, sexual immorality, and licentiousness that they have practiced.
Did you read that scripture? Paul is speaking about those saved REPENTING FROM THE IMPURITY, and SEXUAL IMMORALITY.
REPENTING IS FROM SINS.
