I was talking to an atheist recently who said to me, "I grew up in a devout household. God made me change my mind, I guess." He said this to mock our view of God's sovereignty.
Does God change our minds? Would He make someone not believe in Him? I would respond by saying that He changes hearts, not our minds. All of our hearts are wicked when we come into the world. Therefore, our minds follow along and we feed it with whatever we want and have nothing to do with the holiness of God. But when God changes our hearts, we are made alive to the superiority of the holiness of God and we begin to consciously conform our mind to what He wants and no longer feed it with what our sinful natures want (Romans 12:2).
Take a baby, for example. It is one of the most selfish creatures on earth. It has to be when it's young, but if it's heart isn't changed as he matures, he continues on in his utter selfishness. I've heard it said that an 18 year old with the self-centeredness of an infant would beat and even kill someone who doesn't give him whatever he wants, no matter how small. So, as good parents, we continually train the child as he grows by punishing him when he does wrong. Ultimately, it is his own responsibility whether or not to conform to his parents' training. Many people who come from good homes end up in prison.
We are all born as self-centered babies. If we believe in God and claim to follow Him before He saves us, it's only because of what we think we can get out of Him for our own peace of mind or material satisfaction. Many people choose to believe He doesn't even exist. But when God changes our hearts, then our focus changes to how we can serve Him, even when we have to sacrifice our own desires and material comforts to do it.
I was in a fraternity in college. When I was pledging my fraternity, the brothers would often tell us not to question their reasoning for what they wanted us to do and just trust them because it all had a purpose that would make sense in the end (mine was a music fraternity and didn't do the outlandish kinds of hazing you hear about in the papers). God is infinitely more wise than a fraternity. How much more will the things we don't understand in our earth-bound minds make sense if we trust Him and are finally given to see Him as He is! (1 John 3:2)
