Whenever you offer a prayer, it is received instantaneously by God and his angels, whose job it is to implement your requests, as long as they are in line with God's will.
Because we may not know what is the highest good in a given situation, we should always ask God to adjust our prayers according to whatever is best for our soul or those for whom we are praying.
Our prayers are always answered—but not always in the way we expect.
Sometimes there is a lesson we must learn or there is another solution to the problem we just don't see.
Your request can be as simple as saying, “Let all my prayers be adjusted to God's will.”
