The following posts are from the book "A Lifting Up For The Downcast" by William Bridge.
I have picked out a few paragraphs to give the flavor of the author. William Bridge preached these sermons in 1648, it deals with believers suffering from spiritual depression, and Bridge manifests great inshight into the causes of saints discouragement. He is a true physiscian of the soul. Written in the kings English, if you're not used to it, is somewhat more difficult to follow, but worth it.
“Sin gains not, but is a loser by every fall of the godly. And if you look into the Scripture, you will observe that when the people of God fall, usually they fail in that grace wherein they most excel. Wherein they did most excel, therein they did most miscarry. Abraham did most excel in faith, and therein he did most miscarry. Moses did most excel in meekness, and therein he did most miscarry; we read of no other sin concerning Moses but his anger. Job did most excel in patience, and therein did he most miscarry. Peter did most excel in zeal and resolution for Christ – “Though all the world forsake thee, yet will not I” – and therein he did most miscarry, denying Christ at the voice of a damsel. I say, you will observe this, that the saints fell and failed in that grace wherein they did most excel; and they did most excel wherein they did most miscarry.
What is the reason of this, but because the Lord, by the overruling hand of His grace, did make their very miscarriages, inlets and occasions to their further grace and holiness. God has a great revenue from the very infirmities of His people. He never permits any of His people to fall into any sin, but He hath a design by that fall to break the back of that sin they do fall into. Now, then, have the saints and people of God any reason to be discouraged in this respect?”
