But rejoice, inasmuch as ye are partakers of Christ’s sufferings; that, when His glory shall be revealed, ye may be glad also with exceeding joy. – 1 Peter 4:13

I would not change five minutes of the excessive joy my soul has sometimes felt for a thousand years of the best mirth that the children of this world could give me. O friends, there is a happiness which can make the eye sparkle and the heart beat high, and the whole man as full of bounding speed of life as the chariots of Amminadib. There are raptures and high ecstasies, which on festival days such as the Lord allotteth to His people, the saints are permitted to enjoy. I must not fail to remind you that the Christian is the happiest of men for this reason, that his joy does not depend upon circumstances...A rightly cultivated mind, under the power of divine grace and the exercise of a benevolent disposition affords a ground of satisfaction that is not to be affected by “heres” and “theres.” Every Christian will bear you his witness that he has found his sad times to be his glad times, his losses to be his gains, his sicknesses a means to promote his soul’s health. Our summer does not depend upon the sun, nor our flood-tide upon the moon. We can rejoice even in death. We look forward to that happy hour when we shall close our eyes in the peaceful slumbers of death, believing that our last day will be our best day. Even the crossing of the river Jordan is but an easy task, for we shall hear Him say, “Fear not; I am with thee: be not dismayed, I am thy God; when thou passest through the rivers I will be with thee, and the floods shall not overflow thee.” We dare to say it, then, very boldly, we are not of all men most miserable: we would not change (our joy) with unconverted men for all their riches, and their pomp, and their honor thrown into the scale. ~ C.H. Spurgeon
