Think about it. If we pray for something that is NOT God's will, we're on thin ice.
If we pray for something that IS God's will, He is most likely to answer "Yes."
Not that our prayers are limited to us asking and Him listening.
Prayer, ideally, is dialogue with The Almighty and fellowship with our Creator.
Think of it as "time with your Heavenly Father."
But, what is God's will? Good question!
This we know, His word is His will...
Take a moment to, "Pray the Scriptures." This IS God's will...
