A precious missionary wrote to our ministry about quitting his post. He explained, “I felt as if God had brought me into a wilderness and then left me twisting in the wind. I left the ministry in utter dismay and became bitter. I now see what my problem was. I didn’t put down any roots of trust during my testing time. When the trials came, I didn’t rely on what I knew of God’s Word and his faithfulness. I forgot his promise that he would never fail me.”
