Sometimes you just don’t feel like you have any more love to give. Maybe you’re in a people-intensive job, such as teaching, sales, or customer service, and you come home and think, “I just can’t face another need, another problem, or another heartache.” So you shut down.

Or you need to show love to a particular person who is demanding, acts selfishly, and never returns your love. And you just think to yourself, “I’m done. No more.”

While that’s a perfectly natural and entirely human response, it’s not the standard of love God calls us to in the Bible. The Bible says, “Love never gives up, never loses faith, is always hopeful, and endures through every circumstance” (1 Corinthians 13:7 NLT). Love never gives up.

How can you have that kind of persistent love for another person? You get refueled.

When my kids were young, I remember taking the family to a nearby air show. It was so impressive to see how they would hook up a tanker to a jet in flight to refuel. I’ll never forget that.

But can you imagine someone flying a jet saying, “I don’t need to refuel”? The jet would crash and burn. On a long-distance flight, a jet has to refuel.

To give the kind of persistent love that God wants you to give, you have to refuel your love tank. Look around at society, and you’ll see it’s littered with debris from relationships that have crashed and burned because people didn’t refuel their love.

How do you refuel your love tank? You start by letting God love you. “We love because he first loved us” (1 John 4:19 NIV). When you’re worn out, tired, and unable to imagine showing love to anyone else, remember that God loved you so much that he sent his Son to die for you.

Now that’s real fuel. That’s what keeps you going when you want to quit.
