Charles Spurgeon Commentary 2 Corinthians 4:15-16

"For all things [are] for your sakes, that the grace, being multiplied through the many, may cause the thanksgiving to abound unto the glory of God. Wherefore we faint not; but though our outward man is decaying, yet our inward man is renewed day by day." — 2 Corinthians 4:15-16 (ASV)

For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God. For which cause we faint not;

Paul had said before that they did not faint, and now he reiterates that, though his ministry was enough to bear him down, and lay him prostrate in the dust, yet he did not faint.

For all things are for your sakes, that the abundant grace might through the thanksgiving of many redound to the glory of God. For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.

The sickness that crumbles away the body of a Christian often confirms his soul in the faith that he received when he was strong and well. Some of the healthiest hours that God's people ever have are the hours of their sorest sicknesses. God often sends his people fevers to make them well; he sends them losses to make them rich, he takes away their earthly friends to bring them closer to their best Friend, and he brings them to their wits' end that they may begin to be truly wise.

Often, when God strips us of all our worldly possessions, it is the most soul-enriching season we have ever known; but, on the other hand, the day of temporal prosperity has often been a day of spiritual poverty. Adversity has many times been an angel in disguise, but prosperity has been the devil in a mask. Let us take care that we cleave closely to Christ under both experiences, for then both of them shall be sanctified to us.
