For those who are tempted to think that presenting arguments and evidence is not spiritual because only God can change a rebellious heart, I made two observations. First, without the work of God, nothing else will work — not arguments, not love, not even the simple gospel. Second, with the help of the Holy Spirit, God is pleased to use many things. Love and reason are especially appealing to him because both are consistent with his nature. The fact is, with God’s help, arguments work all the time. Jesus used them, Peter used them, and Paul used them — all to great effect. —Greg Koukl (from, Tactics: A Game Plan for Discussing Your Christian Convictions)
