What a missionary does with his time while traveling full-time on deputation will greatly depend on his family situation, but using that time wisely as a good steward is absolutely necessary. Here are some pointers that my family found helpful to use our time wisely, and yet enjoy the journey when we were on deputation:
Find out what it will cost you to purchase items such as food, office equipment, furniture, transportation, housing, clothing, etc. Find out what things will cost you more there than in America.
One of the best investments you ever make as a missionary could be a planned visit to your field. The money you spend, which may be as much as several thousand dollars, will come back to you many times over.
Deputation looks more difficult than it really is. That is not to minimize the very real challenges. There is a price to pay for this method of raising missionary support—paid with time, finances, physical and emotional drain. But the dividends are great.
