19 The Lord has established his throne in heaven,
and his kingdom rules over all. (Psalm 103:19 CSB)
When we become established in an area we tend to be known by it to some extent. Whether this is in our career or in our personal lives, how we establish ourselves, is how we define ourselves.
God established himself as the ruler of all. I like to say He is; In all, Through all and Over all. This establishes in my mind that there is nothing in my life that God does not have domain over.
Now, He gives me a lot of say in what I do. And more often than not I make bad choices with that freedom. But He gives me that freedom none the less. I am just grateful that He loves me no matter what choices I make.
