Advent is a season when we celebrate the coming of Christ, the hope of the world. As Christians our confidence is rooted in the two comings of Christ. In this series on the book of Revelation, we will explore four roles of Christ during His first and second comings: Alpha and Omega, Pastor of the Church, Lamb on the Throne, and Redeemer. In Christ, we can face the present and the future with peace of mind in the midst of uncertain times.
