Wow, highwayman, that's a very low blow. To prove your argument, you're willing to attack the character of those who disagree with you. Please name one minister or pastor that you know who you trust-- a known minister-- and I can list to you negative things or sins in him or her. You sin too; everyday. Does sin and wrongdoing make a person's teaching or doctrine wrong? When you attack a person's doctrine, you're already in the wrong; but when you attack a person's character and say basically that because they have character flaws, then their doctrines are wrong, then you're really begging God to not forgive your character flaws. You're reproving a person's character and adding claims that most people haven't heard in an effort simply to defend your argument. You apparently cannot see how monstrously evil that is.
You said that those two ministers were found in sin; the implication is that we should reject their testimony, etc. What about ministers who have never been caught in sin or who seem on the outside to be good people? Should we receive all they have to offer? First of all, find me those supposed deathbed confessions. Secondly, ask me about Christians who I've seen who are demonized. If you've already made up your mind what to believe, your pride will not allow you to admit differently. It's not about the Bible but about you being right (or perhaps you not being wrong). When the Pharisees could find nothing wrong with Jesus, they targeted His character; they did the same with Paul and others. If you can prove that a person is bad, then you can get everyone to reject all they have to offer. After all, Jesus' hometown people did it. I know a minister now who is living in sin, and it isn't apparent on the surface; but if the minister preaches from God's Word, then the Lord is present. You can't disqualify a person's preaching or teaching by shining light on character flaws or even sins. It's okay to you because that's how unbelievers and Christians around you operate; but it is criminal as far as God is concerned.
I hope you realize what you're doing and forget about the supposed repentance of Prince and the Hammonds but focus on your own need for repentance. John Bevere has written excellent books; if he was caught in the worst sins, should I decry and disqualify his teachings? When you seek to disqualify the teachings of a minister by attacking or pointing out their character or sins, you are grieving the Holy Spirit. Read about David and King Saul. King Saul was wrong, but when David simply showed less than honorable intentions against Saul (only cut off the edge of his robe so he could show off with it), the Holy Spirit was grieved and struck David with conviction. If you feel justified, get it right before you travel all the way down the wrong way: you aren't. What you're doing isn't holy, but God is and judges us by His holiness and not by our 'good intentions'. Examine yourself to see whether or not you are in the faith. And stick around long enough don't die off yet. In time, demonized Christians will surface everywhere and will be common knowledge. As long as there isn't much of a ministry for them, you won't see them; when genuine ministry comes, just as when Jesus came, then needy people will surface everywhere. At this time, most Christians who know they are demonized hide it because they don't want to be stoned by people like you; others have no idea what is holding them back, why happiness is out of reach, and what seems to constantly be nipping at their ankles. Get your heart right, man. Christianity, contrary to what you know, isn't about right or wrong opinions and doctrines; it's about caring for people because God lives in you.
