21 Then Peter came and said to Him, “Lord, how often shall my brother sin against me and I forgive him? Up to seven times?” 22 Jesus *said to him, “I do not say to you, up to seven times, but up to seventy times seven. (Matthew 18:21–22 Legacy Standard Bible)
Pride is poison to the Christian. Oh, our flesh loves it, but it is unredeemed and has nothing to do with God. On the other hand, all truly in Christ are New Creations (2 Corinthians 5:17) and that part of them that is redeemed is of God not of the flesh and this lost and dying world….
However, all of us would be liars if we said that we have not found ourselves in situations in which we were completely controlled by our flesh and pride. In those situations, we react fleshly just like the world. We lie, cheat, steal, and refuse to forgive when wronged. Then we become bitter and the cycle just spirals downward. All of this happens because we are walking in the flesh with our pride in control instead of in the Spirit, humbly before our God. It is impossible to forgive from the heart without first humbling ourselves and that takes a work of submission to the Spirit of God.
