I Samuel 3:21 And the LORD appeared again in Shiloh: for the LORD revealed himself to Samuel in Shiloh by the word of the LORD.
We all know that Samuel heard from the Lord much more directly than any of us. He even appeared to him in this verse. What strikes me as wonderful is the way that it says God appeared to him by the word of the Lord. I am not sure what that meant for Samuel but I know that for me it means that God speaks to me through His Word.
I believe that God can and does direct us personally. But when He does so it is through using His Word in our lives. There is no new revelation after the Bible. But God does us His Word to speak to us. He shows us His will for our lives. He lets us know what He has in mind for us.
When I feel God directing me I always ask myself if what I am thinking and feeling is in agreement with the Word of God.
