Robert Traill (The Throne of Grace), Works 1:202:
Afflictions are of many sorts and kinds. I am apt to believe, that though there be some likeness in the afflictions of many, yet every afflicted man hath a particular affliction of his own. As it is with people’s faces, so it is with their crosses. For as many thousand faces as are amongst mankind, though all are somewhat like, yet every one hath some distinction. The world is full of crosses; yet every afflicted person hath his own cross. Our Lord hints at it, Matt. 16:24, Let a man take up his cross. The Lord appoints a proper cross for every one: though people are ready to think and say, that their cross is unfit for them, and that they would bear another cross better. In crosses we must neither choose nor refuse. David’s case was singular, 2 Sam. 24. The Lord chooseth for us, and we must not, cannot refuse: Job 34:33, Should it be according to thy mind? he will recompense it, whether thou refuse, or whether thou choose, and not I: therefore speak what thou knowest.
