A 5K race is like the Kingdom of God. Just like in a race there is a starting line, we all have a Spiritual starting line.

Hebrews 12:1=2

God Disciplines His Sons

1Therefore, 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. 2Let 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.
