3 earnestly contend. Used only this once in the New Testament, “earnestly contend” is from the Greek epagonizomai. It was used of athletes intensely agonizing in the grueling training for a coming contest. Jude thus graphically stresses the urgency of defending the faith. Note also Philippians 1:7, 17; I Timothy 6:19-20; II Timothy 4:1-4; Titus 1:9; I Peter 3:15. The defense of the gospel is no indifferent matter, to be left to a few specialists, but one to which all believers should be trained and committed.
