We want badly to be useful to our Master, to fulfill the purpose for which we were created.

“Now in a large house there are not only gold and silver vessels, but also vessels of wood and of earthenware, and some to honor and some to dishonor. Therefore, if anyone cleanses himself from these things, he will be a vessel for honor, sanctified, useful to the Master, prepared for every good work. Now flee from youthful lusts and pursue righteousness, faith, love and peace, with those who call on the Lord from a pure heart.”         2 Timothy 2:20-22
What fuel we feed the engine of our heart will determine how well it will run.
“How blessed is the man who does not walk in the counsel of the wicked, nor stand in the path of sinners, nor sit in the seat of scoffers!  But his delight is in the law of the Lord, and in His law he meditates day and night.  He will be like a tree firmly planted by streams of water, which yields its fruit in its season and its leaf does not wither; and in whatever he does, he prospers.”                    Psalm 1:1-3

Jesus cleanses us with His Word, for the purpose of usefulness for His kingdom.

“You are already clean because of the word which I have spoken to you. Abide in Me, and I in you. As the branch cannot bear fruit of itself unless it abides in the vine, so neither can you unless you abide in Me. I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing.”    John 15:3-5

“. . . Christ also loved the church and gave Himself up for her, so that He might sanctify her, having cleansed her by the washing of water with the word. . .”     Ephesians 5:25-26

Cleanse us, O Lord, as we abide in You, fixing the eyes of our hearts on You, through the medium of Your Word.  Restore us to usefulness for Your kingdom purposes!
