For what the law was not able to do because it was feeble through the flesh, God, sending his Son in the image of the evil flesh, and as an offering for sin, gave his decision against sin in the flesh:
Now this I say: The law, which came four hundred and thirty years after, does not put an end to the agreement made before by God, so as to make the undertaking without effect.
Is the law then against the words of God? in no way; because if there had been a law which was able to give life, truly righteousness would have been by the law.
But now that you have come to have knowledge of God, or more truly, God has knowledge of you, how is it that you go back again to the poor and feeble first things, desiring to be servants to them again?
For the training of the body is of profit for a little, but religion is of profit in every way, giving hope for the life which now is, and for that which is to come.
Do not be turned away by different strange teachings, because it is good for your hearts to be made strong by grace, and not by meats, which were of no profit to those who took so much trouble over them.
