It is said that God wants us to freely choose Him. "God doesn't want robots" is the phrase often bandied about. But often the same people who say this, touting the importance of "free will" also believe that babies, young children and the mentally challenged (if they die) will go to heaven, all of them without question. How does that fit in with the importance of "free will?" If those above go to heaven automatically, then how important really is "free will?"
The theological importance of free will ... or free moral agency ... or the ability to make choices ... resides in the conscious decision to sin, and thereby, responsibility for the guilt of sin. If we have "free will" then we choose to sin, and our sin is our own fault -- and we are responsible for the consequences of our sin. If, on the other hand, we have no free will, and we just do what God has programmed us to do, then we are no more responsible for our sin than a drone or robot is responsible for their actions.
However, I believe that both "free will" and the Calvinistic alternative of non-autonomy are inaccurate.
If we had free will, we could choose to sin all we want, and choose not believe, and still choose not pay the consequences of our sin. The poor person could simply "choose" to be rich. This is not reality. Often, we don't get to make all of our choices. But we do get to make some of our choices.
When it comes to salvation, we are given two, distinct choices. This binary choice is: choose life or choose death. Choose the blessing or the curse.
[Deu 30:19 NASB] 19 "I call heaven and earth to witness against you today, that I have set before you life and death, the blessing and the curse. So choose life in order that you may live, you and your descendants,
God has given the choice structure and meaning. Jesus said "I am the way, the truth, and the LIFE." He was telling us -- if you want to choose life, then choose to believe the good news about Me.
