Then Peter, turning about, seeth the disciple whom Jesus loved following; which also leaned on his breast at supper, and said, Lord, which is he that betrayeth thee. Peter seeing him saith to Jesus, Lord, and what shall this man do? Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me. John 21:20-22
How many times did your parents have to tell you to mind your own business concerning the affairs of your brother and/or sister? How many of you were so concern with what your siblings were told to do that you couldn't carry out the task that had been set before you? Well, look on the bright side (if this is one), you're not the only one.
In John 21:20-22, Peter had been told by God what he should do. Just before he leaves, he turns to see Jesus talking to John (who is said to be Jesus' favorite disciple). Peter ask Jesus about His conversation with John. Now that's bold! Jesus responds to Peter, "If I will that he tarry till I come, what is that to thee? follow thou me."
How ironic is it that we find ourselves doing the same thing Peter did. When we are told to do something, we tend to ask God, "what about them. Why don't they have to go?" Especially if it is somewhere or something we don't want to do. It is so easy to get off our task when we are so focused on someone else. That is not good. If we learn to stay focus on our own business, we wouldn't have time to be concern with anybody else.
Let's take this scripture and use it as a reminder to "mind our own business."
The highway of the upright is to depart from evil: he that keepeth his way preserveth his soul. Proverbs 16:17
