Do you remember the story when Philip was transported away from the Ethiopian after the baptism? If God could do that with a physical body, imagine what He could do to us spiritually?
When we are down and out, depressed, discouraged and wallowing in despair – God can arrive and raise us up and heal us. We could be in the very depth of hell and God will keep us alive so that our testimony is not one of destruction but of salvation.
Our goal is to never be moved, to stand strong. What testimony is there other than God is our helper, His truth is just that – truth.
