Jude 1:20-21

But you, beloved, must build yourselves up on the foundation of your most holy faith; you must pray in the Holy Spirit; you must keep yourselves in the love of God; while you wait for the mercy of our Lord Jesus Christ which will bring you to life eternal.

In the previous passage Jude described the characteristics of error, here he describes the characteristics of goodness.

(i) The good man builds up his life on the foundation of the most holy faith. That is to say, the life of the Christian is founded, not on something which he manufactured himself, but on something which he received. There is a chain in the transmission of the faith. The faith came from Jesus to the apostles; it came from the apostles to the church; and it comes from the church to us. There is something tremendous here. It means that the faith which we hold is not merely someone's personal opinion; it is a revelation which came from Jesus Christ and was preserved and transmitted within his church, always under the care and the guidance of the Holy Spirit, from generation to generation.

That faith is a most holy faith. Again and again we have seen the meaning of this word holy. Its root meaning is different. That which is holy is different from other things, as the priest is different from other worshippers, the Temple different from other buildings, the Sabbath different from other days and God supremely different from men.

Our faith is different in two ways. (a) It is different from other faiths and from philosophies in that it is not man-made but God-given, not opinion but revelation, not guessing but certainty. (b) It is different in that it has the power to make those who believe it different. It is not only a mind-changer but also a life-changer; not only an intellectual belief but also a moral dynamic.

(ii) The good man is a man of prayer. It has been put this way: "Real religion means dependence." The essence of religion is the admission of our total dependence on God; and prayer is the acknowledging of that dependence, and the going to God for the help we need. As Moffatt has it in a magnificent definition: "Prayer is love in need appealing to love in power." The Christian must be a man of prayer for at least two reasons. (a) He knows that he must test everything by the will of God and, therefore, he must take everything to God for his approval. (b) He knows that of himself he can do nothing but that with God all things are possible and, therefore, he must ever be taking his insufficiency to God's sufficiency.

Prayer, says Jude, is to be in the Holy Spirit. What he means is this. Our human prayers are at least sometimes bound to be selfish and blind. It is only when the Holy Spirit takes full possession of us that our desires are so purified that our prayers are right. The truth is that as Christians we are bound to pray to God, but he alone can teach us how to pray and what to pray for.

(iii) The good man keeps himself in the love of God. What Jude is thinking of here is the old covenant relationship between God and his people as described in Exodus 24:1-8. God came to his people promising that he would be their God and they would be his people; but that relationship depended on their accepting and obeying the law which he gave them. "God's love, Moffatt comments, "has its own terms of communion." It is true in one sense that we can never drift beyond God's love and care; but it is also true that, if we desire to remain in close communion with God, we must give him the perfect love and the perfect obedience which must ever go hand in hand.

(iv) The good man waits with expectation. He waits for the coming of Jesus Christ in mercy, love and power; for he knows that Christ's purpose for him is to bring him to life eternal, which is nothing other than the life of God himself.
