You know those prayers that you feel are directly inspired from the Spirit of God? Or maybe a dream with a meaning, or the "God-coincidences" that let you know there is a message He is communicating?
Follow those inspirations to pray as the Lord leads.
The Bible is full of ways God communicated with His people--dreams, visions, parables, angelic visitations etc. Joseph, Daniel, even Nebuchadnezzar received vital communications and warnings supernaturally. Pay attention to His heavenly communications with you!
