"And if anyone forces you to go one mile , go with him two miles." -Matthew 5:41
What does going the extra mile mean? It means that we shouldn't just do what is expected of us, we should willingly do it to our fullest potentiel, we should seek to do more. Notice I said "Seek" and "Willingly," we should "Willingly" "Seek" for the oppurtunity to serve more, and then "Willingly" do it.
"Do all things without Grumbling or questioning." -Philippians 2:14
Here, God is telling us not only to serve and go the extra mile, but to do so without "Grumbling or Questioning." A true servant serves without complaining, he does not question and does not grumble. Jesus was the ultimate servant, never did he complain to God about anything. The Bible calls us to imitate this, to strive to serve like Jesus did. As you probably already know, serving like he did is so hard it is impossible, we will never be perfect, so therefore we will never be able to serve just as Jesus did. But does this mean we give up? No! God never told us it was going to be easy. But he did tell us to serve as much as we possibly can, he has told us to "Do Hard Things!"
"The servant of Christ finds his honour in the service itself." -C.H. Spurgeon
