Because we have seen bazillions of good role models, why not just get rid of all of the things that slow us down and our faults that get us into knotted messes. Let's look constantly to Jesus (the one who created our trust and perfects our trust in him) because he saw the joy (the happy ending) waiting for him and made it through extreme pain and death, laughed in its face, and got to sit down right next to God. Think about him, how he persevered through so many obstacles and so much pain, so that you won't give up when you feel exhausted.
Hebrews 12:1-3 (TPFLV)
