A voice that is silent is not a voice at all.
John the baptist was a voice for the Lord.
Elisha was a voice for the Almighty God.
Isaiah was a voice for the God of Israel.
Apostle Paul was a great voice for the King of Kings.
But the one who represented God perfectly, was Jesus. Are you going to be like Him or not.
Wherever you are tell the world the good knews, that God so loved the world the He GAVE His only beloved Son for us. And whoever believes in Him will be saved.
If don't know Jesus, just ask Him to come into your heart to be your Lord,and He will transform your life completly and make you a child of God.
