As Christians, we are commanded to love one another as Christ has loved us. That should be enough for us to understand that sacrifice is involved - but we often fail to realize that unselfish generosity involves sacrifice. While we wait for Jesus to come again and bring us salvation, we need to follow his command to love one another. We need to be generous with our time, talent, and treasure. And once in a while, we need to be willing to put the needs of others before our own!
