What is at the root of change in the Christian life? The bible is clear that there is no penance, behaviour, work, law, personal goodness or conduct that is possible (or required) to receive God’s gift of salvation. God’s satisfaction rests in the work of Jesus on the cross and our trust (faith) that it is sufficient. So where does the life-changing power the bible speaks of, and all Christians experience come from? If we are saved by grace, why does life-change happen? And what’s at the root of it?
