We should rejoice in our sufferings and tribulations because it is a gift of the Holy Spirit that produces perserverance, character or tried character, and hope.
Perserverance is important because it is the gift of the spirit of long suffering. Perserverance produces tried character because it is a gift that God works in us using the experience of a test. It is a trait that God works in us. Which also gives us the gift of hope. Hope allows us to see our prize at the end..to look forward to the goal in front of us and to keep our eyes firmly ahead.
