Generally whenever the writers of the New Testament quote the Old Testament, it is time to pay attention. However, when they do it TWICE then we really need to take notice:
“Or do you suppose it is to no purpose that the Scripture says, “He yearns jealously over the spirit that he has made to dwell in us”? But he gives more grace. Therefore it says, “God opposes the proud, but gives grace to the humble.” Submit yourselves therefore to God. Resist the devil, and he will flee from you. — James 4:5-7(ESV)
And again:
“Likewise, you who are younger, be subject to the elders. Clothe yourselves, all of you, with humility toward one another, for “God opposes the proud but gives grace to the humble.” Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you, casting all your anxieties on him, because he cares for you.” — 1 Peter 5:5-7 (ESV)
Both of these writers are quoting the Greek text of Prov. 3:34 and it seems like they are trying to say God opposes the proud but gives grace to the humble! So which one will you choose: your own Pride, and therefore being directly opposed by the Living God; or humility and therefore receiving the loving grace and mercy of our God who cares for us?
