We can all pray, “Thy Will be done. It’s all Your Grace. It’s all for good.” We believe it; but when it comes to putting that belief into practice, we might fail because the mind is not yet clean. A prayer is heard if it is uttered even once with a clean mind. Even once. You don’t need to repeat the prayer hundreds of times. No. God is not deaf; there’s no need to repeat it again and again and again. You don’t even need to say it out loud. God knows even your thoughts. But God also knows we are all hypocrites. We don’t really mean what we say. We often pray just for show. God knows all that. So if we say it even once, with complete sincerity, just once—that’s all God needs.
