Many people would like to serve God in some way, but not everyone is usable. Paul described people as vessels in a large house. Some are prized possessions or useful tools to which the owner frequently turns. Then there are other objects in the house that are of no intrinsic value. They take up space but they are of no use. The master of the house might keep them, but he doesn’t use them, nor does he value them.
Some people would like for God to use their life in a significant way, but they never consecrated themselves so they were useful. To be holy is to be set aside for God’s service. It involves being cleansed from sinful habits, actions, and thoughts so we are unencumbered in our divine service. In God’s eyes, it is not just what you do that matters, but how you do it. You can serve God in a selfish or wicked manner, but that is unacceptable to God. God looks for useful, consecrated, instruments.
What kind of instrument are you? Are you one He delights to use, over and over again? Or are you one that remains in the closet, unused, because you have been unwilling to be made holy?
