Regeneration is synonymous with being "born again" and marks the true beginning of the Christian life on earth. Regeneration is the reason why anyone is a Christian, and Jesus explains that being regenerated is a necessary condition for seeing the kingdom of God. Regeneration is therefore critically important and absolutely necessary. So what is it, why does it matter and how is it relevant? This sermon provides clarity and meaningful answers to these questions. Also discussed are the five leaves of Calvin's T.U.L.I.P. (Total depravity, Unconditional Election, Limited Atonement, Irresistible Grace, Perseverance of the Saints). Our Scripture focus will be John 3:1-3.
