Jon 1:12 And he (Jonah) said to them, "Pick me up and throw me into the sea; then the sea will become calm for you..."
Jonah here is a picture of the sacrifice of the Lord Jesus Christ. The storm was ravaging angry against the ship and the people on board felt its fury. They could have all gone down if it continued. Jonah then offered himself to assuage the wrath of the storm and the sea.
It's the same with the Lord Jesus. The wrath of God is blowing angry against us sinners. His justice is hounding us. But the Lord Jesus Christ came and threw Himself, so to speak, on the cross of Calvary and paid the penalty of all our sins.
Putting our faith and trust in Him and what He did on the cross for our salvation, everything changed. God's wrath was appeased. His justice was satisfied. The dark clouds of fear and disquiet within our hearts are replaced by the peace of God. God is smiling.
All because of Jesus who voluntarily offered Himself to die for us. Have you trusted and relied on the Lord Jesus and what He did on the cross?
