If Jesus is a teacher only, then all He can do is to tantalize us by erecting a standard we cannot come anywhere near. But if by being born again from above we know Him first as Savior, we know that He did not come to teach us only. He came to make us what He teaches we should be. The Sermon on the Mount is a statement of the life we will live when the Holy Spirit is having His way with us.
Oswald ChambersNaturally, we are inclined to be so mathematical and calculating that we look upon uncertainty as a bad thing...Certainty is the mark of the common-sense life. To be certain of God means that we are uncertain in all our ways, we do not know what a day may bring forth. This is generally said with a sigh of sadness; it should rather be an expression of breathless expectation.
Oswald Chambers
