Pray and seek contentment where the Lord has placed you in his holy providence. Put your nose to the grindstone, work hard, and leave the results up to him. Whether in plenty or in want, seek to praise Christ in all situations, and don’t compare yourself to others. Pray that you’re faithful to what Christ has called you to do.
In my pre-parent life, I used to have time to run a few triathlons—sprints, mainly. One of the things that I found personally discouraging was the fact that the race event staff would write your age on your calf muscle with a large waterproof marker. At first, it didn’t bother me—I would be cycling or running and I’d see 56, 72, 40, and a host of other numbers higher than my own as I passed them by. As I progressed in the race, however, I quickly realized that for as many numbers higher than my own that I was passing, there were probably more numbers higher than mine passing me by! I saw one woman with 68 on her calf sail by me like I was standing still. It was a bit humbling to have someone double my age smoke me.
I felt a similar sentiment when I was in seminary and later graduate school. There I sat at my desk as my 27th birthday passed me by and I felt like I was standing still. I was still in school, hadn’t done anything significant in my life, and was feeling like many others were passing me. I was sitting in my windowless basement office, single, in a foreign country eating dry cereal for lunch because I couldn’t afford much more. It didn’t help that I knew that John Calvin wrote the first edition of the Institutes by the time he was 27.
