Jude 1:24 Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,
25 To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
It is not we who keep ourselves saved, but God who keeps us.
The dominion and power are his, both now and forever.
This fact is a matter of great comfort and joy to us, and gives us something to hope for, and to believe God for (God's bringing us to faultlessness, that is, perfection).
Already now we can worship and praise God for His glory and majesty, dominion and power (which range from now to forever), and we can also praise God for our own coming perfection. Amen.
