If the soul turn away from Christ righteousness, from being a hearer and doer of God’s law—of His Word, regard iniquity in their heart (mind):
“He that turneth away his ear from hearing the law, Even his prayer shall be abomination.”
Proverbs 28:9 KJV
One who truly hears also will do God’s law. When a soul believes in Jesus, they are hearers and doers of His Word. They are justified by faith, living daily being sanctified by faith, living daily righteousness by faith. There are many professing God with their lips, listening to His Word, listening to His law, going to church, speaking amen, praying—but God says that they deceive themselves; that their prayer is an abomination.
“If I regard iniquity in my heart, The Lord will not hear me:”
Psalm 66:18 KJV
“But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.”
Ezekiel 18:24 KJV
“When the righteous turneth from his righteousness, and committeth iniquity, he shall even die thereby.”
Ezekiel 33:18 KJV
If a soul use to do something that is right doing (by faith, Christ righteousness in the soul), God gave you victory over something; then the soul turns away from right doing and goes backward to that thing—this is turning away from Christ righteousness, turning back to one’s vomit; yet the soul is blinded and deceived and thinks they are ok with God, right with God because they are praying, listening to sermons, even because they are going to church—who truly are they praying to, and worshiping…
Be not deceived. Repent and be converted.
