The author tries to give answers to common problems and proper Christian living. For proper discernment, you need to be Spirit-filled according to God's Word, obeying God's commandments, and not only reading God's Word but doing it. The author was Spirit-filled thirty years after becoming a Christian. The Holy Spirit led him as a missionary to the Philippines, where the Lord established many churches through his mission. These churches are still prospering today, twenty years after the author's retirement.
