Galatians 6

Paul said that we should bear each other's burdens and correct one another in gentleness. If we do so in the Spirit, then we will reap eternal life as a reward, but if we do so of our own accord, the only reward we get will come from ourselves.

More important than what we do is why we do it. If we want God to honor what we do, we must be sure to do it for Him. He does not reward us for doing the right thing for selfish or self-centered reasons. Do everything for the glory of God.
