I read Aventist Frontiers magazine 04.2011 and article written by Gideon and Pam Petersen (Opuwo, Namibia, Africa) captured me.
It is often the nature of missionaries to have martyr spirits, but this trait can be hazardous.
To be effective in ministry, one must stay healthy in mind, body and spirit. Finding balance is essential for sustained ministry. Ellen White cautions: "Man can shape circumstances, but circumstances should not be allowed to shape the man" (Gospel Workers, p. 192) Doing cross-cultural mission work in new environments, one can get caught up in numerous little habits caused by circumstances. The needs are numerous in the community, and people dont know when to stop asking for assistance. Circumstances often dictate that a missionary house is also the missionary office. This blurs the boundary between work and family time. Time management becomes a challenge. Office hours can become 24/7/365, and this is not healthy.
Pray for missionaries that God will give them possibilities to rest and recharge physical, mental and spiritual batteries.
