Romans 12:2 in the J. B. Phillips says, “Don’t let the world around you squeeze you into its own mould, but let God re-mould your minds from within, so that you may prove in practice that the plan of God for you is good, meets all his demands and moves towards the goal of true maturity.”
1 John 1:6 says, “If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth.” We practice truth by bringing it into our lives. It becomes part of our thought processes. Our words and actions reflect our hearts.
Ephesians 3:19 Amplified says, “(That you may really come) to know (practically, through experience for yourselves)…” It is like wallpaper on our hearts.
The truth that sets us free is experiential. John 8:32. The Greek word for know is to perceive, understand, recognize, gain knowledge, realize, come to know. We know our pushy flesh by experience. The Holy Spirit works to bring inner transformation, so that truth becomes an active part of our lives and defeats our flesh.
