To hold on to Jesus is to hold on to reality itself. We are His house. We are His house. If we hold on to our courage and the hope of which we boast. Jesus is our courage and He is the hope of which we boast.
Courage relates to now.
Holding on to Jesus. Fixing my mind on Jesus. Letting the faithfulness of Jesus be demonstrated in how I live my life, and use time, energy, and finances. Such courage means total and unconditional surrender to the Builder. Because He is the greatest, only His will can bring God's glory and greatness to my life.
