Now to Him who is able to keep you from stumbling,
And to present you faultless
Before the presence of His glory with exceeding joy,
To God our Savior,
Who alone is wise,
Be glory and majesty,
Dominion and power,
Both now and forever.
Amen.

Jude: 24-25

After lambasting the ungodly who had “secretly slipped in” (Jude 1:4), explaining the serious nature of God’s judgment, and imploring his readers to live godly lives, Jude ends his epistle with a doxology. Here is where he writes that God is able to keep us from falling. Though Jude tells his readers to “keep yourselves in God’s love” (Jude 1:21), he also points out that it is God who keeps us. Our righteousness does not come from ourselves, but from God. We are to contend for the faith and persevere. But, ultimately, our security does not rest on us. We need not fear that we will fall away from God, for it is He who keeps us upright. We rely on His power, not our own.
