On the importance of prayer:
It is true that Satan seeks to flood the fair garden of the heart and make it a scene of desolation, but it is also true that many Christians leave open the sluice-gates themselves, and let in the dreadful deluge through carelessness and want of prayer to their strong Helper. We often forget that the Author of our faith must be the Preserver of it also…. He who built the world upholds it, or it would fall in one tremendous crash; he who made us Christians must maintain us by his Spirit, or our ruin will be speedy and final. Let us, then, evening by evening, go to our Lord for the grace and strength we need.
(Charles Spurgeon, Morning and Evening, November 15: Evening)
