The worst person who can lie to you is yourself. I’m learning that just because I refrain from any negative thing, say hateful or evil things, or whatever, if I surround myself with these things it still has an affect on my soul regardless if I think it does or doesn’t. So surround yourself with that which is Holy. It doesn’t take much to backslide.
(1Corinthians 6:19-20) 19 Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20 For you were bought at a price; therefore glorify God in your body and in your spirit, which are God’s.
