Thou hast set all the borders of the earth: thou hast made summer and winter.

And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river: for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee.

And the Lord said unto Satan, Behold, he is in thine hand; but save his life.

God is a God of boundaries. In the Bible we see how He defined the limits of the earth and the seasons, set the physical borders for the Kingdom of Israel, and even placed restrictions upon Satan. This is significant, because within boundaries there is freedom. We cannot pass certain borders, but we can move between them as we please. The Summer may be powerful or it may be mild, the Israelites may pitch their tents here or there, Satan may tempt us in one way or another. The choices are open, so long as they do not over-reach.
Thus is God in control? Yes, of course. What else would you describe the being that defines the limits of everything in the universe? But are we also in control? Yes again. Relatively speaking, the bounds that God has set on our lives seem as wide as an ocean, and we are free to steer ourselves within it.
