“Dear friends, although I was very eager to write to you about the salvation we share, I felt compelled to write and urge you to contend for the faith that was once for all entrusted to God’s holy people.” (Jude 1:3, NIV)
In this letter, Jude encourages the disciples of Jesus to “contend for the faith,” because there are individuals and circumstances that would render powerless the Good News — except for the existence of persons willing to make a good stand for the truth.
It is worth noting that Jude says that he would have preferred to write about our common salvation; but that he is, instead, compelled to urge them to stand for our historic faith. The former topic embraces; the latter topic is fists and elbows.
As disciples of Jesus, it is sometimes necessary to take-up the dirty duty of standing for the whole truth, when half-truths are the fashion of the day. Yet, even in such uncomfortable circumstances, remember to stand in the strength of the Lord; to maintain a posture of grace and, when possible, good humor.
There is no higher compliment for a disciple of Jesus than he or she be known as a contender for the historical faith on which we stand. – Luther
