Psalm 29:3 NKJV
The voice of the Lord is over the waters; The God of glory thunders; The Lord is over many waters.
David had a close relationship with the Lord, which can be seen in his writings. It is interesting to see how he talks about the Lord and waters. He speaks of God and His voice over waters. When it comes to the spiritual interpretation of waters, we can see that the Lord speaks by the Holy Spirit in line with His Word. A minister can preach a good and moving sermon, but if it is not based on the Word and there is no anointing on it, it's just the man or woman speaking. When the Holy Spirit is in charge and the anointing is added to the Word, it is God speaking through the person. When the anointed Word goes forth, Jesus shows up and confirms it. So we must never depend solely on our knowledge of the Word when we try to help people. We must seek God's anointing on us to be more effective in helping others. All it takes is asking God to help us and speak through us, then trusting Him to do just that.
Mark 16:20 NKJV says., "And they went out and preached everywhere, the Lord working with them and confirming the word through the accompanying signs. Amen.
