If a man cleanses himself from the latter, he will be an instrument for noble purposes, made holy, useful to the Master and prepared to do any good work.
[2 Timothy 2:21]
Are you keeping yourself polished for the Lord? Impurities exist in lying, lust, short-tempers, laziness, and so forth. These impurities could cause us to be overlooked by God. The special utensil Paul refers to is the silverware that is reserved for special guests and only comes out when company comes over. What an honor it is to be used by God for good work.
