“You may greatly comfort yourself that you have an unchangeable friend in Christ Jesus. From the unchangeableness of your Savior, you may be assured of your continuance in a state of grace. As to yourself, you are so changeable, that, if left to yourself, you would soon fall utterly away. But Christ is the same, and therefore, when he has begun a good work in you he will finish it. As he has been the author, he will be the finisher of your faith.
He will never cease to intercede for you. When once you have entered on the happiness of heaven, it never shall be taken from you, because Christ, your Savior and friend, who bestows it on you, and in whom you have it, is unchangeable. He will be the same forever and ever, and therefore so will be your happiness in heaven.
As Christ is an unchangeable Savior, so he is your unchangeable portion. That may be your rejoicing, that however your earthly enjoyments may be removed, Christ can never fail. Your dear friends may be taken away and you suffer many losses. And at last you must part with all those things. Yet you have a portion, a precious treasure, more worth, ten thousand times, than all these things. That portion cannot fail you, for you have it in him, who is the same yesterday, today, and forever.”
- Jonathan Edwards, “Jesus Christ the Same Yesterday, Today, and Forever”
