"and if children, then heirs--heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him." - Romans 8:17 
How do you enlist suffering to make it your servant? How does one take something that has the ability to take you to the door of entrance to the worst nightmare you could never conceive, which wants nothing more than to seemingly shove you right through that door, and wrap it up in tightly in the firm absolute Hand of God's sovereignty? First, you receive it as a gift from God. Job said, "The LORD gave, and the LORD has taken away; blessed be the name of the LORD." (Job 1:21b). Second, you rely on God's grace because with the gift comes His grace. II Corinthians 9:8 promises, "And God is able to make all grace abound to you, so that having all sufficiency in all things at all times, you may abound in every good work." God is going to be near you in a special way. Finally, reflect on the glory of God. There is no greater Christian who ever lived than the Apostle Paul. His greatest motive in all he endured was the glory of God. His pain became a platform from which he declared the glory of God.
