Exodus 4:6-8 English Standard Version
6 Again, the Lord said to him, “Put your hand inside your cloak.” And he put his hand inside his cloak, and when he took it out, behold, his hand was leprous like snow. 7 Then God said, “Put your hand back inside your cloak.” So he put his hand back inside his cloak, and when he took it out, behold, it was restored like the rest of his flesh. 8 “If they will not believe you,” God said, “or listen to the first sign, they may believe the latter sign.
Some of us have witnessed the affliction of God’s people and their miraculous healing. For those who already believe it is a sign that our faith in Christ is true. For others it is an opportunity to witness the presence of God in the body of Christ. Sadly what God said in verse 8 may have its negative affect. They may not believe the later sign.
I cannot speak to those who are so stiff-necked that they refuse to turn from their unbelief to accept the presence of God in those moments. Does that mean they will not be saved? No, but there can be no salvation without the acknowledgement of the presence of the God of Abraham, Isaac and Jacob.
5 “that they may believe that the Lord, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”
The sole purpose of the signs is to believe in Him who has proven Himself to be that God and no other.
Moses was a witness and spoke for God. Jesus was a witness and spoke for God. The Apostles were witnesses and spoke for God. They all spoke for this God and no other.
Nowhere on earth has any other god proven Himself as God. There is no other God and yet some will refuse the signs before their very eyes.
