In His Word, God commands us to serve one another. However, there will inevitably be difficult people in life who make this mandate challenging.
Thankfully, a biblical definition of service can help us obey the Lord's instruction, no matter who the recipient may be. And the reason is that God is actually the One whom we serve.
When we have this motivation underlying everything we do, it will impact the quality of our work and keep us from becoming discouraged. Then, whatever our task--whether we lead a country, teach children, or do something that seems unattractive--if our goal is to glorify God, we will do our best in His strength. And we trust Him to use us for His purposes, even if our labor should appear fruitless to us or to others.
When I was a child, I had to wake up before daylight to deliver newspapers. Even in rain or snow, I still had to complete the job. This was hard for me to do. Then the Lord impressed upon my heart that I was not merely bringing papers to people in my town; I was serving Jesus. As I understood this truth more, waking up and working was purposeful and doable. Truthfully, I still did not always feel like facing the work, but feelings were no longer relevant. I was serving my Maker.
Whomever God calls us to serve, and whatever He tells us to do, we can obey with joyful hearts when it's done for Jesus. If this is our motivation, we won't need worldly approval or evidence of impact. We need to know only that God is pleased and promises to reward those who serve Him (Heb. 11:6).
