Useful tools. Do you have tools you use around the house because they serve a specific function? I have many useful tools. A lawn mower, computer, a hose, hammer, screw drivers, etc. We have in our home other tools, like a dishwasher, washing machine and dryer, stove, sewing machine, iron, and so on… They are valuable because they are useful.
In Paul’s closing words, he mentions for us a list of faithful servants. These people were about the Lord’s business, doing His bidding, for the common goal of bringing glory to God, and building up the Body of Christ. They are useful for God.
