They need to pray for wisdom and patience. They need to have a long view of who they are in god's plan and of the time and effort it will take for them to develop fruitful work. This will take years, not months or weeks. Time is the price we pay. God has not quit, although the new missionaries may think that is the case.
Servants trust and stay in the background.
God takes clay and turns it into useful vessels. He desires Spirit-filled servants who develop fruit of the Spirit as well as gifts of the Spirit, to advance against the kingdom of darkness. This also takes time. To survive, missionaries need prayer, a willingness to grow, and commonsense expectations. All rights reserved.
