God will either give you what you ask, or something far better.
Robert Murray M’Cheyne
On the ground of our own goodness we cannot expect to have our prayers answered. But Jesus is worthy, and for His sake we may have our prayers answered. But if we trust in Christ, if we hide in Him, if we put Him forward and ourselves in the background, depend on Him and plead His name, we may expect to have our prayers answered.
George Müller
When I stop praying, the coincidences stop happening.
William Temple
