Here are a few thoughts that I have gleaned from a small book entitled SCHOOL OF CHRIST by T. Austin Sparks. It is a booklet mentioned often by Brother David Wilkerson in his sermons and writings. One can ponder just these few thoughts for days!
To learn Christ, we must first see Christ.
The mark of a life governed by the Holy Spirit is that such a life is continually and ever more and more occupied with Christ, that Christ is becoming greater and greater as time goes on.
If we ever come to a place where we think we know, we have it all, we have attained, and from that point we become static, we may take it that the Holy Spirit has ceased operations and that life has become stultified (useless or ineffectual).
If we glimpse so much in Christ that we know we are beaten, that we are out of our depth, and will never range all of this; that it is beyond us, far beyond us, and yet we are drawn on, and ever on, this is the mark of a life governed by the Holy Spirit.
