You hurled me into the deep,It is necessary to point out that God is in control in this situation. Notice that it says, "You hurled me..." Even though we know it was some fishermen that did the deed, Jonah attributes this action to God. Notice also that Jonah attributes ownership of the waves and the breakers to God. God is in control of all things and He owns all things.
into the very heart of the seas,
and the currents swirled about me;
all your waves and breakers
swept over me.
This isn't really all that difficult of a concept to understand. Some tend to make the sovereignty of God into a big debate. They are more concerned about arguing over the fine points or trying to convince others with their eloquent talk, than they are about how God's "in-controlness" is affecting their own daily walk with the Lord.
Whether you can debate it or not, be glad that He is over all. That when the bad stuff happens to us, He is there, He is in control. God never scrambles to fix things. Nothing happens that He hasn't allowed.
Maybe you are in a situation that you have been hurled into. Quite possibly you may feel that the waves and the breakers are pounding you and pushing you under. Whether or not it is for the same reasons as Jonah, turn to God now and acknowledge that they are His waves and His breakers. Trust that He knows what you can handle, and seek His purposes.
