If at the morning dawn we meditate on these things, we shall go forth to our business with much security. If we have first made God propitious by prayer and supplication, going forth thus we shall have no enemy. Or if thou shouldest, thou wilt laugh him to scorn, having God propitious. There is war in the market place; the affairs of every day are a fight, they are a tempest and a storm. We therefore need arms: and prayer is a great weapon. We need favorable winds; we need to learn everything, so as to go through the length of the day without shipwrecks and without wounds. For every single day the rocks are many, and oftentimes the boat strikes and is sunk. Therefore have we especially need of prayer early and by night.
