Faith and good works are in no way mutually exclusive. It is certainly important to stress that we do not come to faith by doing good works, as if we could somehow buy our way into the kingdom of God. But real faith gives rise to good works naturally, just as a tree bears fruit or a vine bears grapes…. Faith, then, is active, seeking to express itself in the way we live, not just the way we think.
