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 21:21-22
My sister has this saying "whatcha care for" when people are asking questions about things that either don't concern them, or they have no intentions of contributing to the cause. We laugh about it so often because people are always inquiring about what other people are doing or have been asked to do instead of doing that which they were told to do.
I think the above scripture is hilarious. Here we have Peter concerning himself with John and what Jesus will have him to do. And Jesus basically telling him, "whatcha care for."
Have you ever found yourself worrying about things that are not of your concern? If we are honest, we all have a time or two. However, Jesus has told us on several ocassions to cast our cares on Him, and not to be anxious for nothing. It is up to us to tend to that which Jesus has told us to do, and not get caught up in the cares of this world, which will profit us nothing. Our desire and goal should be to get into the kingdom of God by being obedient to His Word. I have found that to be challenging enough by itself than adding other people's issues to it. BE BLESSED!
Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. Philippians 4:6
