Many missionaries dislike furlough.
It should be seen as a time to sow for a fresh harvest of involvement from the home churches in the field of your calling. No seed in spring will yield no harvest in the autumn. It is a time to convey that there is more to be done. It is a time to declare the faithfulness of the Lord while showing the fruit of their involvement thus far. It is a time to challenge a new generation of believers to embrace opportunity by sending finances and people to your field.
