God a liar? Never
1 John 1:10 If we say that we have not sinned, we make Him a liar, and His word is not in us.
I dont ever want to call God a liar. That is quite the charge. It also would prove His word is not in us because He would never lead us to such conclusions. His word exposes our true motives and then we can get those selfish, sinful things squared away. We only tell truth when we speak what God speaks.
