When God gives us a revelation about someone, it is not up to us to make that person confess to us, or to condemn them.
God reveals truths to us so that we can trust him and his judgement, and for discernment, to know the truth of God, and the lies of Satan. We are not to take what God has given us and use it for our advantage, which it is truly, a disadvantage.
God wants us to trust Him, not use him. When we use God, we are mocking God, and there is a penalty for mocking Him.
Use the revelation that God gives you to glorify Him, not yourself. Remember, it’s always between you and God, not you and the other person.
Ephesians 5:6 (KJV) – let no man deceive you with vain words: for because of these things comets the wrath of God upon the children of disobedience.
Galatians 6:7 (KJV) – be not deceived; God is not mocked; for whatsoever a man soweth, that shall he also reap.
I Peter 2:12 (KJV) – having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.
