When we give someone a present, we hope they’ll like it. But we don’t accompany the recipient to see if the present is being used properly. It would be impertinent on our part to require an accounting of the use of the present.
For certain men have secretly slipped in among you — men who long ago were marked out for the condemnation I am about to describe — ungodly men who have turned the grace of our God into a license for evil and who deny our only Master and Lord, Jesus Christ.
Jude 4 NET
The grace of God is the present, or gift, of salvation, as well as the divine empowerment to fulfill his mission in the world. Different from human relationships, this grace makes us administrators responsible for its use. God requires faithfulness in the gift of salvation and in the gifts (talents) of empowerment.
This is why Jude condemns false teachers for the abuse of God’s grace. This condemnation serves to warn all today who would turn God’s grace into a motive for serving one’s own interests and giving oneself over to the passions of the flesh. For among us, those who would abuse this grace are growing. They should be exposed and rejected in our midst, in the same way that Jude recommends that his brethren resist such intruders in the church.
