“Prayer is a mighty instrument, not for getting man’s will done in Heaven, but for getting God’s will done on earth.” ~ Robert Law
1 John 5:14 (KJV)
And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
Phil. 4:6 (KJV)
Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
