Matthew 5
Matthew 6
Matthew 7
7:24 “Therefore everyone who hears these words of Mine and acts on them, may be compared to a wise man who built his house on the rock. 25 And the rain fell, and the floods came, and the winds blew and slammed against that house; and yet it did not fall, for it had been founded on the rock. 26 Everyone who hears these words of Mine and does not act on them, will be like a foolish man who built his house on the sand. 27 The rain fell, and the floods came, and the winds blew and slammed against that house; and it fell--and great was its fall.”
If saving faith is just "trust in the cross" how to make sense of Jesus' sermon on the mount?
Honestly I don't know if I can live up to what Jesus says in this sermon ...
Man is
obligated to be righteous/obedient! Always has been, since Eden. But he can only accomplish this to the extent that he's in relationship/communion with God. That's the basis of the New Covenant; that's what Adam missed and, in fact, denied and
dismissed with his act of disobedience. But,
"Apart from me you can do nothing" (John 15:5). We're all here to learn this simple and vital truth, with the help of revelation and grace;
man needs God.
So when the time was ripe in human history Jesus came to definitively introduce us to the true and living God, so we can know Him and so come to believe in Him and enter communion
with Him as is the right and just order of things for man.
"Now this is eternal life: that they know you,the only true God, and Jesus Christ, whom you have sent." John 17:3
We just need to experience a bit of life in the pigsty for awhile so we may learn of the relevance and seriousness of Jesus' words in John 15:5. So that we
want to know Him. This is meant to be a cooperative effort between man and God, which is why God didn't simply stock heaven with the elect and hell with the reprobate to begin with. Instead He
draws us towards the light, most brilliantly shown by His act of self-sacrifice on the cross, an act that places love squarely at the forefront of His motivation-and at the forefront of His will for us to have as well.
Love fulfills that obligation to be righteousness, which is why love is said to fulfill the law. It excludes sin by its nature, the two being mutually exclusive. Paul understood this as 1 Cor 13 makes clear. And Augustine could accurately say, "Without love faith may indeed exist, but avails nothing." But we have to want it, to hunger and thirst for it enough to turn to, and remain with, Him.
