Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, 2 looking unto Jesus, the [a]author and [b]finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God.
3 For consider Him who endured such hostility from sinners against Himself, lest you become weary and discouraged in your souls.
Hebrews 12:1-3
As Christians, all are a witness to our walk, every word and deed. I have heard it said that we may be the only bible anyone may read, so we must run this race well. Our full focus must be on Christ in whom our faith is complete, and endured the cross to the point of death so we may live life to the full.
