Jude 3-4

v3: “Those who have received the message of salvation must contend for it” because Satan has instruments and agents that he uses to corrupt the faith. “The busier and more scheming” those whom Satan uses are, “the more careful we should be” to hold firmly to the truth.

v4: The presence of “dangerous errors” that undermine any “essential article of the Christian faith” and which would cut us off from Christ, provide fresh “opportunity for the proper defence of important truths.” Let’s be grateful for those whom God uses to spot those subtle error that creep in, and who help us to become more acquainted with the truth as revealed in Scripture.
