Dr. Craig Keener, professor of New Testament at Asbury Theological Seminary, discusses the miraculous works of God today. He looks at both Scriptural arguments and church history evidence of such realities in a massive tome called Miracles (1200+ pages). You can also view short video bytes where some points are briefly looked at, these being more easily digestible. And, even more, Keener is one that was a bit more skeptical about miracles still being a part of life today. Needless to say, God slowly changed his mind.
Below is one of those short videos.
