God's written Word is the known, sure, absolute, revealed Will of God! It's all there, all you need to know is already there in the Bible! Look in His Word, at all He's said before! If God never tells you another thing, if you never get a revelation, if you never hear a voice, if you never get a prophecy, if you never have knowledge, if you never have wisdom, if you never have discernment, if you never have the gift of healing, if you never have the gift of miracles, if you'll just operate according to the written Word of God, you'll accomplish a whole lot!
Jesus said, "Heaven and Earth shall pass away, but My Words shall never pass away!" (Mat.24:35) "Forever, O Lord, Thy Word is settled in Heaven!" (Psa.119:89) There's no question or any doubt about it! You can count on God's Word!--It never fails! "How firm a foundation, ye saints of the Lord, is laid for your faith in His excellent Word! What more can He say than to you He hath said, to you who for refuge to Jesus have fled!"
When He speaks to you right through His Book, you know it's right!--So look to the Word!--Amen?
