If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth. 1 John 2:4

“They profess to know God, but by their actions they deny Him. They are detestable, disobedient, and unfit for any good deed. No one who remains in Him keeps on sinning. No one who continues to sin has seen Him or known Him.”
