Charles H. Spurgeon on Psalms 119:81

My soul fainteth for thy salvation; but I hope. Believe under a cloud, and wait for him when there is no moonlight nor starlight. Let faith live and breathe, and lay hold of the sure salvation of God, when clouds and darkness are about you, and appearance of rotting in the prison before you. Take heed of unbelieving hearts, which can father lies upon Christ. Beware of "Doth his promise fail for evermore?" for it was a man, and not God said it. Who dreameth that a promise of God can fail, fall a swoon, or die? Who can make God sick, or his promises weak? When we are pleased to seek a plea with Christ, let us plead that we hope in him. O stout word of faith, "Though he slay me, yet will I trust in him!" O sweet epitaph, written upon the gravestone of a departed believer, namely, "I died hoping, and my dust and ashes believe in life!" Faith's eyes, that can see through a millstone, can see through a gloom of God, and under it read God's thoughts of love and peace. Hold fast Christ in the dark; surely ye shall see the salvation of God. Your adversaries are ripe and dry for the fire. Yet a little while, and they shall go up in a flame; the breath of the Lord, like a river of brimstone, shall kindle about them. Samuel Rutherford, 1600-1601.
