For I know the thoughts that I think toward you, says the Lord, thoughts of peace and not of evil, to give you a future and a hope. -Jeremiah 29:11

God giveth His beloved the sleep of quietness of soul as to the future. O that dark future! that future! The present may be well; but ah! the next wind may wither all the flowers, and where shall I be? Clutch thy gold, miser; for “riches make to themselves wings and fly away.” Hug that babe to thy breast, mother; for the rough hand of death may rob thee of it. Look at thy fame and wonder at it, O thou man of ambition! But one slight report shall wound thee to the heart, and thou shalt sink as low as e’er thou hast been lifted high by the voices of the multitude. The future! All persons have need to dread the future, except the Christian. God giveth to His beloved sleep with regard to the events of coming time.

What may be the future lot,
High or low concerns me not;
This doth set my heart at rest,
What my God appoints is best.

Whether I am to live or die is no matter to me; whether I am to be the “offscouring of all things,” or “the man whom the king delighteth to honour,” matters not to me. All is alike, provided my Father doth but give it. “So He giveth His beloved sleep.” How many of you have arrived at that happy point that you have no wish of your own at all? It is a sweet thing to have but one wish; but it is a better thing to have no wish at all-to be all lost in the present enjoyment of Christ and the future anticipation of the vision of His face. O my soul! what would the future be to thee, if thou hadst not Christ? If it be a bitter and a dark future, what matters it, so long as Christ thy Lord sanctifies it, and the Holy Ghost still gives thee courage, energy, and strength? ~ C.H. Spurgeon
