Everything we have is a gift from our Heavenly Father. Scripture says "What do you have that you did not receive? If then you received it, why do you boast as if you did not receive it?" (1 Corinthians 4:7). In response to what we have been given we are invited to give, "not reluctantly or under compulsion, for God loves a cheerful giver" (2 Corinthians 9:7).
The death, burial, and resurrection of Jesus represent the most generous gift ever given. When the King of Glory gave up everything in order to reconcile us to God. Giving cheerfully, sacrificially, and consistently is a part of our worship. When we give generously, we remind one another of the great generosity of our good Father.
