"We love because Christ loved us first." 1 John 4:19
There can be many motives for serving others. Maybe we see a need, or feel guilty, or are looking for a way to feel better about ourselves. However, God calls us to serve for a different reason: because he first served us through Jesus, we now serve as a way to obey him and model our lives around the life of his Son. So, the Christian motive is different; we don't serve to work off a guilty conscience, or as a means of gaining accepting or feeling superior, but as a example of the grace we have experienced.
We encourage every Christ-follower to joyfully serve others as a response to the grace they have received. This doesn't have to be done "at church" (in a specific building or organization), but if you're looking for ways to serve, here are some of the things we're involved with as a faith family.
