That on Pentecost God’s Spirit should function through a dozen seeming inebriates should be no surprise when this same God saves through the ignominy of the cross.
Although God is always closer to us than the nose on our face, he has not taken the wraps off and given any sinful and mortal human being a full-measure, face-to-face meeting.
Paul wants us to see this “present evil age” is dominated by a theology of glory and “the age to come” is dominated by a theology of the cross. They are two ways of understanding and interpreting all of reality, but especially the ways and nature of God.
