God's voice is powerful for God is all powerful. His voice awakens, convicts, stirs, calls and warns. Isaiah 30:30 through the powerful majestic voice of the Lord the Assyrians were defeated. John 11:43 Lazarus came forth out of the tomb when Jesus' voice was heard.
In Genesis 1:3 God said, let there be light. His voice created the earth, skies and mankind. Psalm 29:4 The voice of the Lord is powerful and full of majesty. 5, The voice of the Lord breaks the cedars. 7, The voice of the Lord divides the flames of fire. 8, The voice of the Lord shakes the wilderness.
There are many voices in this world. Some are deceptive and tormenting. God's voice speaks truth and comfort. When we read the Bible the Holy Spirit can give direction and wisdom. God's voice speaks through Scripture telling us to believe in Him. Christ is the one who died on the cross and rose again. There is power in His shed blood for the forgiveness of our sins. He is the true Shepherd of our souls.
John 10:27, My sheep hear my voice and I know them and they follow me. Follow Christ and allow His Spirit to direct your paths. Let His voice speak through you telling others about Him.
