The London Marathon takes place today. To complete it requires determination and much effort. So it is spiritually if we are to cross the finishing line into glory. See below for your edification:
24 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. 25 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. 26 Therefore I do not run like a man running aimlessly; I do not fight like a man beating the air. 27 No, I beat my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize. 1 Cor 9v24-27
12:1 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. 2 Let us fix our eyes on Jesus, the author and perfecter of our faith, who for the joy set before him endured the cross, scorning its shame, and sat down at the right hand of the throne of God. 3 Consider him who endured such opposition from sinful men, so that you will not grow weary and lose heart. Heb 12v1-3
5 Similarly, if anyone competes as an athlete , he does not receive the victor's crown unless he competes according to the rules. 2 Tim 2v5
I have finished the race, I have kept the faith. 8 Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day--and not only to me, but also to all who have longed for his appearing. 2 Tim 4v7-8
