What God Promises People Who Keep Showing Up

If you are tired of serving others and wondering whether it will ever pay off, Scripture's answer is not "try harder." It is "wait well." The apostle Paul writes, "Let us not grow weary in doing good, for in due season we will reap a harvest if we do not give up" (Galatians 6:9). The harvest is real. The timing simply is not ours to set.

That is a hard word in a culture that has largely forgotten how to wait. Delayed gratification is a lost art, and that is not a new observation. But it is worth sitting with, because almost everything that wears us down in serving other people traces back to a question about waiting.

What the Marshmallow Test Says About Waiting

The most famous study in the field of delayed gratification was done in 1970. Dr. Walter Mischel, a psychologist, developed a practical test he called the marshmallow test. He put a group of first graders into a room one at a time. On the table in front of each child sat a single marshmallow.

He placed the marshmallow there and laid out two choices. The child could eat it immediately. Or the child could wait fifteen minutes, and when he returned there would be a second marshmallow to go with the first. But if the child ate the marshmallow, there would be no second one waiting.

What he found is that waiting is tough. Many of the children ate the marshmallow the moment the door closed behind him. Straight off the table and into the mouth.

Several waited. And Mischel did not stop with that single afternoon. He expanded the study and followed those first graders through life, tracking them one step after another. Here is what he found: the ones who waited found greater success. Higher test scores. Better quality of life. Better life skills in general, measured against those who did not wait.

The Two Questions Underneath Every Wait

Strip that experiment down to its heart and you find two questions that every waiting person is quietly asking.

The first is a question about the person making the offer. Can I trust the one who is making the promise? Is he of such a character that I can be sure waiting will be worth it? A promise is only ever as good as the one who makes it. A child sitting in front of a marshmallow has no history with the man who just walked out the door. All the child has is his word.

The second question is the corollary to the first. Is the promise worth waiting for? Even a trustworthy person can offer you something that does not justify the cost of waiting. Fifteen minutes is a long time when you are six years old and the payoff is one more marshmallow.

Both questions land squarely on the Christian life. When we are tired of doing good, when the serving feels thankless and the harvest feels imaginary, we are not usually having a theological crisis. We are having a trust crisis. We are asking whether God is who He says He is, and whether what He has promised is actually better than what we could grab for ourselves right now.

Is God's Promise Really Worth the Wait?

Here is what I want you to hear. The promise that waits for all of us because of what Jesus has done on our behalf is far superior to anything we can gather now. Not slightly better. Far superior.

That is why Paul can say what he says." Let us not grow weary in doing good, for in due season we will reap a harvest if we do not give up." The instruction only makes sense if the harvest is real and the One promising it is trustworthy.

Then Paul finishes the thought in the next verse with a statement that reframes everything about how we spend our ordinary days. Serving people is service to Christ.

Why Serving People Is So Hard

Over the years, young men and women have come to me and said, "I'd really like to do what you're doing." I always ask them the same thing. How do you feel about people? How do you feel about serving people?

Some of them are honest with me. Not so great, they say. People are messy. I just want to stand up and preach like you do.

Let me tell you, one of the hardest realities of the job I do is that people are indeed messy. You have probably noticed that too. And if you have not noticed it, you are probably one of the messy ones. I say that in jest, because the truth is that all of us are messy. Every one of us, just in our own particular way.

And yet consider what Jesus came for. Luke's Gospel says He came to seek and to save that which was lost. The messy ones. The ones who did not have it all together. The ones who were broken, who made mistakes, who did things out of order, who colored outside the lines. Jesus came for them.

Now our commission, our calling, the command of Christ to us, is to do likewise.

Wouldn't it be much easier if we didn't have to? Maybe so. But it wouldn't be much like Jesus either.

Questions Worth Asking Yourself

So let's turn our attention back to ourselves, because this is where the waiting gets personal and practical.

Am I willing to get messy, to bear the burdens of somebody else? Not the tidy version of service that fits neatly into a calendar, but the kind that costs something and does not resolve on schedule.

Am I willing to let faithfulness be better than success? Those two are not the same, and in seasons of waiting they can feel like opposites.

Am I planting what I actually hope to get back? Or am I planting something I do not want and quietly hoping it never comes to fruit?

If you are worn out in doing good, the invitation is not to grit your teeth harder. It is to look again at the One who made the promise, weigh what He has actually promised, and decide that He is worth the wait. In due season, you will reap a harvest. Do not give up.
