“Be Holy and Useful to Christ 要成為聖潔，合基督使用“（2 Timothy 提摩太後書2:20-21）
In a large house there are articles not only of gold and silver, but also of wood and clay; some are for special purposes and some for common use. Those who cleanse themselves from the latter will be instruments for special purposes, made holy, useful to the Master and prepared to do any good work.
Christ’s church is indeed an immeasurably large house because of greatness in its owner, its planned/designed scale, its building cost and its significance. In such unique house of a variety of ‘articles/members’ (Christians), some are for special purposes and some for common/dispensable use. In view of God’s general cleansing for sin, all Christians are the same, not some better (or more spiritual) than others. One cleansing oneself is mostly connected with usefulness for service and closeness to God. Some Christians are more able to be used by God than others because they have cleansed themselves and made themselves more usable to God, in the sense of not only serving in the church but also doing any good work.
Prayer: Father God, many of us might not have made necessary effort to appreciate how great your earthly family house is and what role we should play in it. Thank you for reminding us that it is left to us what and how we want to play our role. Our conduct – clean or unclean; set apart to you or not set apart to you; useful to Jesus Christ or not useful to Him – really matters. It greatly effects if you can use us or not and how you will use us to touch the lives of others. Amen.
