Joshua 1:8 This Book of the Law shall not depart from your mouth, but you shall meditate in it day and night, that you may observe to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success.
God speaks to us through His Word and work in us by the spirit. You cannot hear him minus His Word. Psalm 119:105 Your word is a lamp to my feet And a light to my path.
