According to the Bible, Jesus forgives us for any sin. Yes, including murder. 1 John 1:9 says, “If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness.” Yes, that includes murderers. Jesus Christ came to redeem us from EVERY lawless deed (see Titus 2:13-14).
In the Old Testament, David slept with Uriah’s wife, Bathsheba, and then had Uriah killed in battle (2 Samuel 11). In 2 Samuel 12:13, God forgave David. The text says, “And David said unto Nathan, I have sinned against the Lord. And Nathan said unto David, The Lord also hath put away thy sin; thou shalt not die.”
The Book of Mormon also teaches that murderers can be forgiven. Alma 24:10 says,
“And I also thank my God, yea, my great God, that he hath granted unto us that we might repent of these things, and also that he hath forgiven us of those our many sins and murders which we have committed, and taken away the guilt from our hearts, through the merits of his Son.”
3 Nephi 30:2 agrees, saying,
“Turn, all ye Gentiles, from your wicked ways; and repent of your evil doings, of your lyings and deceivings, and of your whoredoms, and of your secret abominations, and your idolatries, and of your murders, and your priestcrafts, and your envyings, and your strifes, and from all your wickedness and abominations, and come unto me, and be baptized in my name, that ye may receive a remission of your sins, and be filled with the Holy Ghost, that ye may be numbered with my people who are of the house of Israel.”
I agree with the Book of Mormon. While the Book of Mormon says that murder can be forgiven, other Mormon doctrine in their other Standard Works says the sin of murder cannot be forgiven. The book Doctrine and Covenants, one of the 4 books of canonical scripture in the Mormon Church, used to be called the Book of Commandments in 1833 (before it changed names in 1835). Book of Commandments, 1833, 47:2-3 says,
“And it shall come to pass, that if any persons among you shall kill, they shall be delivered up and dealt with according to the laws of the land; For remember, that he hath no forgiveness.”
Today’s Doctrine and Covenants 42:18 says,
“And now, behold, I speak unto the church. Thou shalt not kill; and he that kills shall not have forgiveness in this world, nor in the world to come.”
Joseph Smith taught,
“Remission of sins by baptism was not to be preached to murderers. All the priests of Christendom might pray for a murderer on the scaffold forever, but could not avail so much as a gnat towards their forgiveness. There is no forgiveness for murderers.” (Discourses of the Prophet Joseph Smith, 221)
The 12th Mormon president-prophet, Spencer W. Kimball taught,
“The Prophet Joseph Smith underlined the seriousness of the sin of murder for David as for all men, and the fact that there is no forgiveness for it.” (The Miracle of Forgiveness, 128)
These Mormon teachings are deluded, and the case is clear: murderers can be forgiven by the blood of Jesus Christ!
