Good on you David. Keep it up.
"The Law of the Lord is perfect, restoring the soul" Ps 19:7
"Through the Law comes the knowledge of sin." Rom 3:20
Some people will try to delete the commandments saying they no longer matter. They say we no longer need to leave our sins. They teach false teachings even though they have been shown verses that tell the truth. And yes, there are verses that say to be saved, we need to believe, but then they ignore the rest of the bible. "This people honours Me with their lips, But their heart is far away from Me. And in vain do they worship Me, Teaching as doctrines the commandments of men." These people override the commands and ignore them. If we truly believe our sin put Jesus on the cross, then we will want to leave it. We would not want to put another nail in the cross. True belief will have actions with it and so we will leave our sin.
