Because of the prevailing environment in Jude’s day—which included “ungodly” spiritual leaders who were promoting damaging doctrines (1:4)—he wrote an urgent, intense letter to believers in Jesus whom he addressed as “dear friends” (vv. 3, 17, 20), sometimes translated “beloved.” He strongly urged the believers “to contend for the faith that was once for all entrusted to God’s holy people” (v. 3). The King James Version uses stronger language, rendering the Greek word epagōnizomai as “earnestly contend.” It means “to struggle for,” “to exercise great effort and exertion for something.” It was used of athletic contests to describe the struggle and effort expended by the athletes. The faith refers to the teaching of Christ and the apostles that was believed and practiced by His followers. Today, God will help those who’ve heard and responded to the truth of Scripture to earnestly “contend for the faith,” remain faithful, and encourage others who are being deceived by false teachers.
