There are different levels of being good at something. For example, you might be good at math in that you can balance your checkbook. However, you probably aren’t good enough at math to be a rocket scientist who works for NASA.
This principle holds true in many ways. You may be a good enough teacher to convey some biblical truths to people in everyday conversations, but not good enough to teach a class in your church. You might be a good enough singer to blend your voice well with the congregation on Sunday morning, but not good enough to sing a solo. You might be good enough with babies to make a little one smile for a moment, but not good enough to be in charge of the church nursery for a full hour.
We need to be honest with ourselves as we assess what we do for the Lord.
“For by the grace given me I say to every one of you: Do not think of yourself more highly than you ought, but rather think of yourself with sober judgment, in accordance with the faith God has distributed to each of you.”—Romans 12:3.
