Did you read ALL of D&C 132? No. If you had read it all, you would have taken note that it said nothing at all about Emma being "angry" with Smith. You're twisted statement is based on you wanting to believe the Lord was telling an angry Emma, angry at what you believe were adulterous actions of Smith that Emma became wise to, that made her angry so verse 56 to you is about Emma's anger for Smiths adultery and the Lord telling her to cool it and forgive him.D&C 132
56 And again, verily I say, let mine handmaid aforgive my servant Joseph his trespasses; and then shall she be forgiven her trespasses, wherein she has trespassed against me; and I, the Lord thy God, will bless her, and multiply her, and make her heart to rejoice.
What trespasses would she be angry about if it wasn't adultery?
Like I said, nice twist.
D&C 132 says nothing of Emma being angry nor of Smith having committed adultery. It does state that as the Lord forgives them both their trespasses, that he wan't Emma to forgive Smith his trespasses and wants Smith to forgive Emma her trespasses.
Read the information as it was written before you foolishly twist it to your wants and needs.
