wattie,
The theory that repentance is just a form of mental understanding with no impact on life is the saddest definition I here from time to time. The sad companion theory is the "repentance" is only "deciding" to change your mind about Jesus. That net effect of that theory is we are free to live however the heck we please because at some time in the past we changed or mind about who Jesus was. Thus, Christianity is entirely theoretical mental/emotional experience where you came to believe a 60 second pulpit prayer made you right with God for eternity....guaranteed. IMHO, the most fundamental error in this framework is that it requires you to reinterpret the entire Hebrew Bible and the rest of the New Testament.
Let's start with your example of "God repented of what He did with Israel. In no case did God "repent" of what He did to Isael.
Exodus 32:14: After the Israelites worshipped the golden calf, God told Moses He would destroy them. Because Moses interceded and prayed for the people, "the Lord repented [relented] of the evil [calamity] which he thought to do unto his people" Under your theory, the prayers of the people for forgiveness were not sufficient. Only Moses had standing to ask for mercy. This demonstrates God's "repentance" is a change of action not theory.
King Saul (
1 Samuel 15:11): God stated that He regretted making Saul king because Saul turned away from following Him and disobeyed His commands. (this opens the door to reimaging how God works in the world where He can regret His own choices)
Amos 7:3,
6: The prophet Amos pleaded with God to forgive Jacob (Israel) from coming locusts and fire, and the text notes that "the Lord repented" and said it would not happen. Again the plees of the nation of Israel where not enough to get God to change His mind, only the individual prayer of a holy man prophet God listen to.
Jeremiah 18:8: God explicitly states that if a nation turns away from its evil, He will "repent [relent] of the evil [disaster] that I thought to do unto them" Thus repentance means turning away from evil.....not just a mental exercise.
The Bible also teaches in places like
Numbers 23:19 that God is not human and does not lie or change His ultimate mind. Various theology traditions have arisen to explain that God's eternal character and plans never change, but He uses human language to describe how His unchanging mercy interacts with changing human choices in history. This means that human choices of actions, lives and hearts are in play in the definition of repentance.... not just making a personal change of mind....without physical demonstration.
I though Billy Graham had a pretty good sense of what real repentance is:
"The dictionary defines repent as “feeling sorry or having regret.” But the words Jesus spoke meant a great deal more. The Biblical word repent means “to change or to turn.” It is a word of power and action—signifying a person’s complete turnabout. Jesus calls us to repent, turn away from sin, and walk in the opposite direction from sin and all that it implies.
When the Prodigal Son realized that he had sinned against his father, he got up and left the pig pen of sin and returned to his father. He didn’t just feel sorry for his sin. He wasn’t passive about it. He turned his feet in the other direction and headed home. He sought out his father and humbled himself before him, and then he was forgiven.
Many professing Christians don’t follow what the Bible teaches as repentance, thinking that it is little more than shaking their heads over their sins and saying, “I’m so sorry I did that,” and then continuing to live just as they had lived before. It’s possible to be convicted of sin and even shed tears over sins, and yet not repent.
Not one verse in the Bible indicates a person can be a Christian and live any kind of life he or she wants. When Christ enters into the human heart, He expects to be Lord and Master. He commands complete surrender. He requires that we be subject to Him, and He empowers His people to seek His desires.
