I think the greatest gift I have received through my challenges is a heart of thanksgiving. Because I was once in great lack, I am so very thankful for everything I have. Because I have battled sickness I am so very thankful for my health. Because I have felt great pain and disappointment, I am so very thankful for the joy of the Lord which is my strength.
Psalm 100:4 says; Enter into His gates with thanksgiving, And into His courts with praise. Be thankful to Him, and bless His name.
Colossians 3:15 says; and let the peace of God rule in your hearts, to which also you were called in one body; and be thankful.
