Rebellious people fake good character because they know their sinful heart is not acceptable. So...instead of asking Christ to change their heart, they simply pretend in front of people to feel validated by others and even deceive themselves into thinking they can fool God.
Ezekiel 36:25-27 "…25 "Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. 26 "Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. 27 "I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances."
God wants us to desire for Him to change our heart. When we confess sin, it is strong evidence that we really hate what we are and want Christ to change us into the new creation.
Pretenders and fakers are people who are so stubborn they would rather put on a false mask than submit to Christ so that He can change them. Submitting to anyone is abhorrent to them, even though they will shout hard and long how they obey God and follow all the rules. When in company with those who are submitted to God, they work to make these people believe they are submitted when they are not in the least matter.
Stubborn and rebellious people become enraged when they are challenged to look at their own lives, because they need desperately to maintain the false self. Why? The false self is the one they like, the selfish 2 Timothy 3 self is the one they prefer, but it doesn't get along too well with others, so they must put up the mask to pretend in front of others.
Sadly, these pretenders don't have faith to believe in God Who sees all that they do. The fact that they refuse to be evaluated and convicted by the Word of God, demonstrates that they are willful and stubborn.
When we know Who God is and what He is capable of, we are very concerned about what He sees in us.
Proverbs 1:7
"The fear of the Lord is the beginning of knowledge; fools despise wisdom and instruction."
I have heard rebellious people quote the Proverbs verse about the fear of God while they live in rebellion to Him. Here again we have a situation where words are enough in the mind of rebellious people because the "appearance" is all that matters to them.
Psalm 33:8
"Let all the earth fear the Lord; let all the inhabitants of the world stand in awe of him!"
Those that fear the Lord are easily convicted by the smallest sin, hating it, admitting it and turning from it, they hear the voice of the Holy Spirit.
So what is wrong with a rebellious person who seems to have no conscience over the things they do? I believe the answer is clear, those who cannot hear God or be convicted by their sin, were never born again. They never exhibited any form of remorse for their bad behavior and they never apologize for anything. These people are deathly afraid that their inner heart will be discovered. They refuse to discuss anything out of fear the real self will slip out for all to see.
Proverbs 3:7
"Be not wise in your own eyes; fear the Lord, and turn away from evil."
There is only one hope for these lost and empty souls, that is to turn to Christ, confess their sin of pride, ask the Lord to change their wicked hearts and begin to grow in the power of the Holy Spirit.
