Many people around the world are afraid right now. It is a natural emotion. I believe that Jesus, in His human form, was afraid when He walked this earth. He must have been afraid in the garden of Gethsemane when He asked God to take the suffering away. Also, when on the Cross and He believed God had abandoned Him.
Can you imagine that? The Son of God believing that His Father had abandoned Him?
In both occasions when Christ was afraid, I believe it was the devil tempting Him. Just like he is tempting many of us to be afraid of our current situation.
