Prayer

Why do I not think of what deserves to be asked for, before even beginning to pray?
Should I go into a store, as Spurgeon says, without having in mind what it is I need?
And why do I pray halfheartedly for a thing, and without it being resolved, move on to the next?
I must learn to stop and fervently pray for someone until I'm convinced God will save or deliver or mature them, until moving on to the next.
When I hear stories about people praying through the night and getting 3 or 4 hours of sleep, because they count prayer as immensely more valuable... I look at my own schedule and know that things have to change.
My heart and attitudes toward people have been affected by my prayer life, most of all my heart toward God.
