There are some things we want to do but simply are not equipped to accomplish. I, for example, have the desire to sing. The problem is, I am what you might call a jailhouse singer – I never have the key, and I’m always behind a few bars. Paul gives good advice in Romans 12:3: “Have a sane estimate of your capabilities” (PHILLIPS). In other words, be aware of your strengths. When you teach, do people listen? When you lead, do people follow? Where are you most productive? Identify your strengths, and—this is important—major in them.
We cannot meet every need in the world. We cannot please every person in the world. We cannot satisfy every request in the world. But some of us try, and in the end we run out of fuel. So have a sane estimate of your abilities and stick to them.
