Connecting with one another opens room for the power of the Holy Spirit. That power is released through the gifts, natural abilities, and good and bad experiences each of us has had. We all have something of value to offer, and nothing short of the transformation of the world is at stake. Meaningful work is important to having a meaningful life; contributing what you have to the transformation of the world is as meaningful as it gets.
There is more going on when we serve, though. When we respond in service, we find ourselves back at worship, discovering the love of God from the other side as we express love to others with no expectation of repayment. To respond is its own reward; it elevates our ability to praise the worthiness of God.
