When we come to the New Testament interpretation of our Lord we find He is not a Teacher, we find He is a Saviour. We find that His teaching is but a statement of the kind of life we will live when we have let Him re-make us by means of His Cross and by the incoming of His Spirit. The life of Jesus is to be made ours, not by our imitation, not by our climbing, but by means of His Death. It is not admiration for holiness, nor aspirations after holiness, but attainment of holiness, and this is ours from God, not from any ritual of imitation.
...[F]or the instruction and courage of those whose hearts are fainting in the way, ...to whom life holds out no more promises, ...let me bring the message contained in this Psalm [121], even as a cup of water from the clear sparkling spring of life. 'My help cometh from the Lord who made heaven and earth.' He will take you up, He will re-make you, He will make your soul young and will restore to you the years that the cankerworm hath eaten, and place you higher than the loftiest mountain peak, safe in the arms of the Lord Himself, secure from all alarms, and with an imperturbable peace that the world cannot take away."
Excerpt from
Oswald Chambers, The Place of Help: A Book of Devotional Readings
(New York: Grosset & Dunlap, 1936) 5-6
"[W]e sooner or later learn that if Jesus Christ was merely a Teacher, He adds to the burdens of human nature, for He erects an ideal that human nature can never attain. He tantalizes us by statements that poor human nature can never fit itself for. By no prayer, by no self-sacrifice, by no devotion, and by no climbing can any man attain to that 'Blessed are the pure in heart,' which Jesus Christ says is essential to seeing God.
