Think about Jesus as He faced the cross to purchase our redemption. That is, the possibility of redemption for all those lost in the world. He saw everyone who would believe and receive His New Covenant in His blood. Hebrews 12:1–2 brings focus to what Jesus endured in Gethsemane:
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, looking unto Jesus, the author and 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.
Hebrews 12:1–2 NASB
Jesus understood the implications of His up-coming death on a Roman cross. The writer of Hebrews encouraged us to: “fix our eyes on Jesus, the author and perfecter of faith,” (Hebrews 12:2a NASB). We are to throw off everything that hinders our race. We must run with perseverance the full distance. That is, persevere in spite of the length of the race, the difficulty of the course, the boredom of repetition, the hindrances that come our way, and the sin that so easily entangles us along the way.
