So shall My word be that goes forth from My mouth;
It shall not return to Me void,
But it shall accomplish what I please,
And it shall prosper in the thing for which I sent it.
–Isaiah 55:11 (NKJV)
If you want to see your prayers work, the best thing you can do is find a scripture for what you need. Why? God tells us in Isaiah that God’s Word always come back with something. Praying some flowery prayer for world peace will get you no where. Praying according to God’s Word will take you places and give you results.
