The human heart...

Referring to Bible reading and prayer, John Piper says:
“I earnestly recommend that it be in the early morning, unless there are some extenuating circumstances. Entering the day without a serious meeting with God, over his Word and in prayer, is like entering the battle without tending to your weapons. The human heart does not replenish itself with sleep. The body does, but not the heart. We replenish our hearts not with sleep, but with the Word of God and prayer.”

Yep. This is something my mind, and my heart have been mulling over lately. I think I've been winning the battle, but I pray that God helps me to continue. And boy, what a difference it does make.
