Baptism is a unifying aspect of Christianity (Ephesians 4:4), and as such, the vast array of viewpoints on the topic make Jesus' prayer in John 17:21 a seeming impossibility. What does the Bible say about baptism? . . . 1 Peter 3:21.
It is biblical to raise your hands during worship (though certainly not mandated). . . . Galatians 4:6-7.
Christ is the point of the Bible, even in places where He is not explicitly named. . . . Mark 1:1-8.
In his book, "The Church: The Gospel Made Visible," Mark Dever seeks to help us clearly understand the importance of the local church.
This book “addresses how denominational affiliation can be natural without being negative, and how evangelical identity can help rather than hinder Christian unity.” -- from Why We Belong, edited by Anthony L. Chute, et al.
