Paul wraps up his letter to Titus with a final encouragement and an exchange of greetings. His final statement is his common expression of grace.
See this passage at Titus 3:14-15:
Paul gives Titus one last instruction in the first verse of this passage. He states that “Our people too must learn to devote themselves…”
This untranslated “too” ties this statement directly to the one before it where Paul tells Titus to help meet the needs of Zenas and Apollos. The believers on Crete, as well as you and I, must learn to meet the needs of others and do good works. This is not simply limited to the two men who brought Paul’s letter to Crete, but should be a way of life for all believers, meeting the needs of those around them.
Paul expands this though by giving two purposes for these good works.
They help provide for daily necessities
These are the things that we need each day to function. The idea behind this phrase means pressing needs or urgent necessities. In classical Greek, the idea is that of the necessary things of life. This would include things like food, clothing and shelter, but wouldn’t necessarily be limited to that. Indispensable wants would also be included in this idea as well.
They help us to not live unproductive lives
When we see and grasp each opportunity to do good works, we become fruitful. Paul encourages Titus to teach the believers on Crete to learn to seize these opportunities as they occur. Producing fruit is an indicator of our faith. If we do not display fruit, we show that we are not growing, and in John 15, Jesus warns that the unproductive branches will be pruned.
