The definition of girding up your mind is ready to work. We won’t always understand why God is calling us to obey Him, but it is so He can do His work in our lives.
Personal holiness is living a holy life in our body, mind and spirit. Sanctification is making the ordinary things holy because we are doing them for God. Everything about us is set apart for God to use.
Living in light of Christ’s return. The essence of the Christian life is to turn to God from idols, serve and wait for the return of Christ. Living clean and holy before God and others.
