Wow, that's the first statement of God's sovereignty I've seen by a Catholic in a long time.
It’s implicit in everything that we do.
That’s why we have a crucifix. It is an ongoing reminder of what the sacrifice of Christ means. God is our Master. But it is because we are willing, not because He ordained it secretly, not because we are robot slaves, but because we make a daily effort to love Him and fallible as we are, we will do our best each and every day.
We are servants, not slaves. We are not mindless insects, nor are we preprogrammed mechanical devices. We choose God, or not. And that is how the Bible is supposed to be interpreted.
