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, to the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen. ~ Jude 1:24,25
Beloved, have you never sat down and reflected on the doctrine of the perseverance of the saints? I am sure you have, and God has brought home to you a sense of your security in the person of Christ. He has told you that your name is graven on His hand; He has whispered in your ear the promise, “Fear thou not, I am with thee.” You have been led to look upon Him, the great Surety of the covenant, as faithful and true, and, therefore, bound and engaged to present you, the weakest of the family, with all the chosen race, before the throne of God; and in such sweet contemplation I am sure you have been drinking some of the juice of His spiced pomegranates; you have had some of the choice fruits of Paradise; you have had some of the enjoyments which the perfect saints have above in a sense of your complete and eternal security in Christ Jesus. Oh, how I love that doctrine of the perseverance of the saints! I shall at once renounce the pulpit when I cannot preach it, for any other form of teaching seems to me to be a blank desert and a howling wilderness—as unworthy of God as it would be beneath even my acceptance, frail worm as I am. I could never either believe or preach a Gospel which saves me today and rejects me tomorrow—a Gospel which puts me in Christ’s family one hour, and makes me a child of the devil the next—a Gospel which justifies and then condemns me—a Gospel which pardons me, and afterward casts me down to hell. Such a Gospel is abhorrent to reason itself, much more it is contrary to the mind of God whom we delight to serve. Yes, beloved, we do enjoy a sense of perfect security even as we dwell in this land of wars and fightings. ~ C.H. Spurgeon
