By perseverance the snail reached the ark. – Charles Spurgeon

Do you not know that in a race all the runners run, but only one gets the prize? Run in such a way as to get the prize. Everyone who competes in the games goes into strict training. They do it to get a crown that will not last, but we do it to get a crown that will last forever. (1 Corinthians 9:24-25, NIV)

Perseverance means more than endurance— more than simply holding on until the end. … Faith is the supreme effort of your life— throwing yourself with abandon and total confidence upon God. — Oswald Chambers

Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God. (Hebrews 12:1-2, NIV)
