1 John 1:10 NIV If we claim we have not sinned, we make him out to be a liar and his word is not in us.
I have known a person who says “I have not sinned and I am sinless”. That’s extremely brave statement, isn’t it? In other words, that person is telling I’m absolutely perfect and declaring that God is a liar! And in reality, the Word of God has no place in his heart. So, I counsel you to confess (tell it and surrender it to God) your sins (1 John 1:9) and open youp heart and receive God’s Word and you’ll not be changed.
