The power of the Spirit
This is very cool to me...I'm reminded of Stephen and Peter preaching in Acts and the power in which was spoken. Stephen was unreal as he unfolded the story of the OT thru to Christ, before he was stoned. Also too, to come to that point where you stand before rulers and authorities preaching Christ shows a complete submission to the Holy Spirit in your life. So it only makes sense that it that moment the Spirit would place words on your lips...
