As you wish that men would do to you, do so to them. Including weekly Sabbaths, Israel was on holiday about 80 days out of a year. It's better to wear out than to rust out. The ladder to glory has rungs of suffering. Suffering produces endurance.
Endurance produces character.
Character produces hope. Hope cannot disappoint us, because with it we get the guarantee, God's own holy Spirit, through which God's love is poured into our hearts. Consider it all joy when you fall into all kinds of trials, knowing that the part of your entrustment to God which has been proved creates the capacity for endurance. Then let endurance see you through to its final conclusion. Then God will have made you mature and complete, lacking nothing.
