Since you spent all of that money at Moody Bible College and don't know what the biblical meaning of repentance is, how about I contact Moody and at least demand a partial refund back for you?
Never been to Moody Bible College, nor do I know anything about them, you prig.
"A biblical definition of repentance is to make a change of mind"
If you had stopped there, you would have been correct, but like every other false teacher, you added to the gospel. You sound like a disciple of the godless heretic, Ray Comfort.
by turning away from sin and self and returning to God
First of all, repentance has nothing to do with doing something about sin, that is blasphemy. Jesus died for our sins, and only He is qualified to do anything about sin. Nowhere in the Bible does it say anything about repenting from sin to be saved. In fact, like a blind squirrel finding a nut, you accidently posted the verse that tells us what repentance is, but it has nothing to do with doing something about sin.
"And saying, The time is fulfilled, and the kingdom of God is at hand:
repent ye, and believe the gospel."
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.
