This verse tells why we are still here. In other words, you were saved to serve.
Service is one of the evidences of salvation.
God has a plan for every individual Christian's life and serving is in that plan. Christian service is vital for spiritual growth. Without it we become preoccupied with our own needs, our own problems, our own situations. The result is we become self-centered, insensitive, and mean. Serving others helps us get our minds off of ourselves.
