1. The problem with repentance
In his book Destined to Reign Prince says this about repentance
"For all of you who feel that there should be more preaching on repentance, do you know what the word ‘repent' means in the first place? The word ‘repent' is the Greek word matanoeo, which according to Thayer's Greek Lexicon, simply means ‘to change one's mind.' But because we have been influenced by our denominational background as well as our own religious upbringing, many of us have the impression that repentance is something that involves mourning and sorrow. However, that is not what the Word of God says. Repentance just means changing your mind."
Prince is not being honest with the Greek word metanoeo. Here are the Strong's definitions of the word
Greek Definition
g3341. μετάνοια metanoia; from 3340; (subjectively) compunction (for guilt, including reformation); by implication, reversal (of (another's) decision): — repentance.AV (24) - repentance 24;a change of mind, as it appears to one who repents, of a purpose he has formed or of something he has done
Notice the word compunction in the definition. Here is the English definition for compunction:
Webster -Compunction: a feeling of guilt or regret ( chiefly US)
Full Definition
1 a : anxiety arising from awareness of guilt b : distress of mind over an anticipated action or result 2 : a twinge of misgiving : scruple synonyms see penitence, qualm com·punc·tious -shəs adjective
So, to repent does not just simply mean "to change ones mind." There is much more to it than that. The word that Prince used in his above statement makes this even more clear.
Repent: metanoeo: "to think differently or afterwards to reconsider (morally feel compunction) To change ones mind. To change ones mind for the better, heartily to amend with abhorrence of ones past sins."
As you can see, this definition means more than simply "to change ones mind.
