Hebrews 11:4

Hebrews 12:1
Therefore, since we are surrounded by such a large crowd of spectators [Note: Christians are pictured here as being in a crowded arena, performing in the games], we should lay aside every [excessive] weight and sin that so easily entangle us, and with perseverance, we should run the race [of life] that lies before us.
