The Bible teaches that God is merciful and gracious, slow to anger and freely offering salvation for all those who will believe. While He is all of those things, He also says in His Word that his mercy will come to an end for those who continually hold onto their sin and refuse to repent. The day of judgment will be a terrible one for those people, so the plea remains: repent, believe, and receive His mercy that can change your life from the inside out.
