Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight and the sin that clings so closely, and let us run with perseverance the race that is set before us, looking to Jesus the pioneer and perfecter of our faith, who for the sake of the joy that was set before him endured the cross, disregarding its shame, and has taken his seat at the right hand of the throne of God. Consider him who endured such hostility against himself from sinners, so that you may not grow weary or lose heart. (Hebrews 12:1-3, NRSV)
Fix your eyes upon Jesus the author and perfector of our faith is how I remember learning this verse, back when I was 17. Jesus was the one who created our faith and he perfected it in the man who walked this earth and showed us how to love and live the law of God. Jesus went to the cross for each for us. So we should follow his example.
If you can’t see the back of Jesus’ head, your focus is off and you aren’t looking the right way.
Fix your eyes on the cross and know He will never lead you astray.
