Because our God is ALREADY in our tomorrow, we will not worry, we will not fear - we will set our heart and our mind on Him, we will place our hope, trust and faith in the Sovereign King, He will take care of us. Remember GOD IS ALREADY in our tomorrow so we can rest in Him, rest in His promises, rest in & on Him.
Our Father is already and because He is already there, that means provision is already there, a way out is already there, protection is already there!. He is a good Father and a God of preparation - nothing catches Him off guard.
Rest in the Lord and Hope in God!!
