Sovereignty is such a religious word. But I take it to mean the power of a sovereign, or king or ruler. God's sovereignty is such an important part of our knowledge of Him. We declare His sovereignty and power in creation and history and we give Him sway as sovereign over our lives when we submit to Him. But have we considered that we declare His sovereignty by believing in the smallest things? Conversely we deny it by lack of faith in those things. Here is what I mean:
Some people say that they do not think we should bother God with what they call 'trivialities'. They think in trivializes God and our faith if we ask God for a parking space when we shop; or to help us not spoil the cake we are cooking; or to find our golf ball we just sliced into the bushes; or to help us find just the right dress at just the right price. But in fact, we do the exact opposite by not praying at these times. To say that God our Father is not interested in the least of our activities and thoughts, is to say that He is not Lord of absolutely everything.
God controls all things in all details. When was the last time you and I limited His sovereignty in our lives? Have we lifted our voices singing 'How Great Thou Art' but in our heart have said, "But you can't even help me find my lost wedding ring". When you are driving around looking for a parking space, say, "Lord, I believe in Your sovereignty, please find me a parking space, in Jesus mighty Name!" - then believe in His sovereignty over details and keep driving until you find it. That faith in small things will make us faithful in much.
