Hebrews 12:1, 3

Therefore, since we are surrounded by so great a cloud of witnesses [who by faith have testified to the truth of God’s absolute faithfulness], stripping off every unnecessary weight and the sin which so easily and cleverly entangles us, let us run with endurance and active persistence the race that is set before us

Just consider and meditate on Him who endured from sinners such bitter hostility against Himself [consider it all in comparison with your trials], so that you will not grow weary and lose heart.
