Christians view giving as a spiritual practice, not as philanthropy. We don’t give “our time, our talents, our gifts, our service, and ourselves” primarily to support the church, though of course this often happens. We give as a sign that all that we have belongs to God, and that we trust God’s provisions even as we live more simply. We give to return thanks to God for God’s self-giving love in Jesus Christ.
Mostly, however, Christians give because, in giving, God changes us. God uses our small, human acts of sacrificing time, talents, gifts, and service to make us more like Jesus, to mold us into people whom John Wesley said bore a “family resemblance” to Christ, so that we too become God’s vessels of grace in the world. We give as a sign that, in the life, death, and resurrection of Jesus Christ, God’s unstoppable, self-giving love makes new life possible.
