This collection of 37 evangelical studies of an apologetic nature is the result of two years of hard work. In it I have succeeded in developing some basic concepts such as: saving faith, effective baptism, the church of Christ, resurrection of the dead, salvation by the righteousness of God, and the bearing of the cross. I have been able to draw a line, God willing, between Law and Grace. Among the studies that reveal hidden secrets in the Scriptures, I cite: the Parable of the Weed, The 144,000 Virgins, The Great Whore, The Lord Our Righteousness. What is amazing is that the Grace system appears as a new Law, the Law of Christ. Several studies are devoted to preparing God's people for the coming persecutions.
