Yes!! We can be expectant that God will do great things! This is the essence of resting in Him! I will remain confident of this: I will see the goodness of the Lord in the land of the living!
I don't have to worry because I know my father will use all things for my good!
Isn't it so great that we have the privilege of actually casting our cares on Him because He cares for us and are actually encouraged to not worry because He will take care of us!? What an awesome Father we have! :D
