Saturday or Sunday. Which day is the true Sabbath, the day that God set aside at Creation to worship Him? Does it matter which day we worship on? Does God require us to worship on a certain day, or is He content that we are simply worshiping Him? Many Christians have questions regarding the Lord's day, and fortunately, the Bible has the answers. The Truth Behind the Lord's Day puts aside the opinions of man and turns to the Bible for guidance on this important subject. The book presents a thorough Bible study about the Sabbath, looking at the Old and New Testament to discover its origin and its place in history before and after Jesus' death. In addition to examining the Bible, the book presents a historical overview of the early Christian church and the practices of the apostles regarding Sabbath observance. In-depth information about the history of Saturday and Sunday worship guides readers toward a clearer understanding of the biblical Sabbath, which was designed by God for mankind. Join Pedro Prestol on this exciting theological journey through the Bible and early church history. Discover for yourself the true Sabbath according to the Bible and God's call for all Christians to worship Him on His appointed day.Pedro has studied and continues to study the Bible since he was a child. It is his desire to share the knowledge he has obtained from the study of the scriptures, as many churches today do not teach the truths found therein and instead teach doctrines of man. Today, Pedro is fulfilling the Bible Prophecy of the Three Angel's Message "And I saw another angel fly in the midst of heaven, having the everlasting gospel to preach unto them that dwell on the earth, and to every nation, and kindred, and tongue, and people..." (Rev. 14:12)
