All things shall work together for your good

The ancient apostles walked and talked with Christ. They testified that He lived, but they also saw firsthand that He died and they knew it with certainty. How terrible to witness of that death and yet how important that they be able to testify absolutely that He died, for otherwise their testimony of His living again would have been questioned and doubted! God made to "work together for your good" the pain of the apostles' experience. God can make our pains and suffering serve high purposes, His purposes.
