As we move into Exodus 4.1-17, Moses is prepared for the task given to him in chapter 3. He is given powerful signs to authenticate the truth claims he is making about God, such as,
…So he threw [his staff] on the ground, and it became a serpent…v.3,
…he put his hand inside his cloak, and when he took it out, behold, his hand was leprous like snow.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…vv.6-7,
…you shall take some water from the Nile and pour it on the dry ground, and the water that you shall take from the Nile will become blood on the dry ground…v.9.
It’s so important when we see miraculous events like this in the Word we consider why they are happening, and, often, if we read carefully we will see,
…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…v.5, cf. John 20.30-31
When we see miraculous events, they always testify to a truth claim about the Lord. Here, it was to verify that Moses was the guy chosen to lead in this particular period of time, and that the Lord was with him.
The same is true for Jesus, read Mark 2.1-12, for example.
What this means for you is that Jesus authenticated His claims with miraculous, unexplainable, wonderful works in order to show that what He said was true, is true.
For you, this means that when He says He loves you, He means it.
When He says your sins are forgiven, He means it.
When He says that He came to give you life abundant and life eternal, He means it.
He’s established that whatever He says is true, comes true, and is nothing but true, and that is great news for you!
