You preach the same kind of repentance that the apostle Paul said was a false repentance.
"Now I rejoice, not that you were made sorry, but that your sorrow led to repentance. For you were made sorry in a godly manner, that you might suffer loss from us in nothing. For godly sorrow produces repentance leading to salvation, not to be regretted; but the sorrow of the world produces death."
Judas "turned away from sin" feeling sorrow for what he had done, and then he went and killed himself, because no man can justify himself through his behavior.
"Then Judas, His betrayer, seeing that He had been condemned, was remorseful and brought back the thirty pieces of silver to the chief priests and elders, saying, “I have sinned by betraying innocent blood.” And they said, “What is that to us? You see to it!” Then he threw down the pieces of silver in the temple and departed, and went and hanged himself."
Judas attempted to repent from his sin, but that is a false repentance, the same repentance you preach. The only true repentance was exhibited by the thief on the cross, who could do nothing about his sin, so he turned (repented) and believed in the One who did everything about sin.
YOU have never done this. You are a Judas.
