Charles H. Spurgeon on Psalms 85:6

Truly sin kills. Men are dead in trespasses and sins, dead in law, dead in their affections, dead in a loss of comfortable communion with God. Probably the greatest practical heresy of each age is a low idea of our undone condition under the guilt and dominion of sin. While this prevails we shall be slow to cry for reviving or quickening. What sinners and churches need is quickening by the Holy Ghost. William S. Plumer.

Verses 6-7. Wilt thou not revive us, by the first and spiritual resurrection, and so thy people, quickened from a life of sin to a life of grace, will rejoice in thee, not in themselves, presuming nothing on their own power. And in order that these things may be fulfilled in us, Shew us, O Lord, thy mercy, that is, Christ, through whom thou hast pitied the human race, shew him to us after this exile that we may see him face to face. Richardus Hampolus.
