The waters wear the stones: thou washeth away the things which grow out of the dust of the earth; and thou destroyest the hope of man.

For a righteous man falls seven times, and rises again. [Proverbs 24:16]

Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints. (Ephesians 6:18)

It is perseverance that leads to great accomplishments.

In the confrontation between the stream and the rock, the stream always wins, not through strength but by perseverance.

For thine own purpose, thou hast sent The strife and the discouragement!
