This attempt to capture the distinctiveness of Wesleyan theology:
A Generous Tradition
God is Love
Cross is Love
You can see how central human free will is to a Wesleyan view of the world. To be sure, Wesley did not believe in anything like absolute free will, where we have complete control over what we want and do. Wesley believed that our ability to make moral choices was a gift from God, empowered by God's prevenient grace, a grace that finds us when we are not seeking it.
Indeed, if we have a spark of free will inside, it must surely be a miracle. The more we understand the brain and human psychology, the more we realize the extent to which "who we are" is a function of the physical structure and chemistry of our brain, the harder the idea of human freedom becomes. And the debate has moved beyond whether our actions are determined or free. Quantum physics has pushed the issue beyond whether our desires are "determined or free," to the sense that they are random, chaotic, and unpredictable.
At the same time, more than Wesleyan thinking is at stake. The greatest objection to the truth of Christianity is the problem of evil, why God allows evil to continue in the world. The best answer, although it is not perfect, is that a world in which people have freedom to make moral choices is a better world than one in which they do not. Christian traditions who do not believe in human freedom run the risk either of making God the direct author of evil or making him unjust himself, views which seem to render Christianity incoherent.
The belief that God has created a world where humans are free to follow or not follow him has implications for the way we live. The Wesleyan tradition, when it is consistent with itself, is thus not oriented around forcing others to conform to Christian values. To be sure, it has always been active in stopping the oppression of others. But it is not like other traditions that view wrongdoing primarily through the lens of offending God. It does not try to legislate Christian morality beyond the protection of others. Its prophetic voice to those outside the church is more for others than against sin.
We thus relate to others in a different way. The parent does not get enraged because the child has disobeyed, an effrontery to authority. The parent is concerned for what the child will become, and disciplines to try to steer the will of the child in the right direction. Discipline is formative not summative. It is about formation more than about punishment. The best of the Wesleyan tradition will thus live out its sense of God empowered human freedom from a motivation of love.
