Cast thy burden upon the Lord, and he shall sustain thee; he shall never suffer the righteous to be moved. (Psalm 55:22)
It is a heavy burden; roll it on Omnipotence. It is thy burden now, and it crushes thee; but when the Lord takes it, He will make nothing of it. If thou art called still to bear, “he will sustain thee.” It will be on Him and not on thee. Thou wilt be so upheld under it that the burden will be a blessing. Bring the Lord into the matter, and thou wilt stand upright under that which in itself would bow thee down.
Our worst fear is lest our trial should drive us from the path of duty; but this the Lord will never suffer. If we are righteous before Him, He will not endure that our affliction should move us from our standing. In Jesus He accepts us as righteous, and in Jesus He will keep us so.
What about the present moment? Art thou going forth to this day’s trial alone? Are thy poor shoulders again to be galled with the oppressive load? Be not so foolish. Tell the Lord all about thy grief and leave it with Him. Don’t cast your burden down and then take it up again; but roll it on the Lord and leave it there. Then shalt thou walk at large, a joyful and unburdened believer, singing the praises of thy great Burden-bearer.
