Jude 1:21

Keep yourselves. Although Christians are “kept by the power of God” (1 Peter 1:5; cf. on John 17:11), they also have to keep themselves from all evil and to stay in the sphere of good influences (cf. on 1 Tim. 5:22; James 1:27; 1 John 5:18, 21).

In the love of God. That is, within the orbit of God’s love for man. Those who remove themselves from God’s protective love, as did the false teachers, cannot expect to be guarded from evil. For comment on the love of God see on Rom. 5:5; 1 Cor. 13:1.

Looking for. Gr. prosdechomai, “to expect” (cf. on Titus 2:13). Compare on 2 Peter 3:12.

Mercy of our Lord. Scripture generally speaks of the mercy of God (cf. on Eph. 2:4; 1 Peter 1:3), but Christ, being of the same nature as the Father, is no less merciful. This attribute, on which our future depends, will find the acme of its fulfillment at the second coming, when the Lord returns to redeem those who have accepted the eternal life that His mercy has provided. The Christian, therefore, eagerly looks for this fulfillment.
