- Is there a Biblical basis for the belief that God does not forgive the sin of murder, no matter how repentant the murderer is?
- These quotes seem to indicate that there is no repentance (and therefore forgiveness) unless one does not commit the sin again (ever). So, let’s say I commit the sin of lying. I repent. What if I lie at some point later in life. Does that mean that I wasn’t forgiven when I repented the first time? Is this what he meant by it taking years to know that we have been forgiven?
In answer to your questions that I numbered (1) and (2):
(1) Yes:
1 John 3:15 Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.
Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
Murderers (i.e. premeditated first degree murder) will be rescued from hell if they are repentant, but not in the sense of gaining eternal life in the Celestial Kingdom. They lost that opportunity by the choice they made to take the life of another of God’s children.
(2) I don’t know if by your example you meant “habitual lying” or “telling a single lie”. The degree of the sin would of course be dependent on the motives, the impact on others, and the intent of the person afterward if they attempted to right the wrong through telling those who were impacted by the sin, and asking their forgiveness.
If (in your example) you repented including asking the forgiveness of those impacted, and then much later your new episode of lying was with different people, then the steps one would follow to receive forgiveness for that new episode are the same as before.
If the new episode was with the same person as occurred the earlier time, then it can be assumed that the earlier repentance wasn’t “complete” in that the resolution to never commit the sin again was not kept. Sincere and complete repentance implies a real, heartfelt commitment to change behavior that really does result in a change in behavior–but that may take more than one episode where the person realizes they are going to need more help from the Savior than they may have earlier realized, so they “dig deeper” into their soul and make a deeper commitment to change behavior.
Sometimes, chronic behavioral issues such as habitual lying may require years of showing the behavior has been completely changed, such that the person knows deep inside that they have made that change totally and feel renewed, and thus their repentance is complete and they are right with God and others and they will know it in their heart.
