"A spiritual gift is a skill that the Spirit anoints to be effective. The effect is not always just conversions. It's the pricking of consciences. It's the deepening of love for the Lord. It's the correcting of behaviour in others".
John Piper in Justin Taylor and John Piper (editors) - "Stand: A Call for the Endurance of the Saints" - Crossway Books (2008) - (p140).
