() A Colorado father who murdered his pregnant wife and two young daughters in 2018 believes God has “forgiven” him.

Chris Watts, who is serving a life sentence at Wisconsin’s Dodge Correctional Institution, wrote in prison letters that he is a “new creature,” per the Daily Mail.

Watts confessed to strangling his wife, Shanann, who was 15 weeks pregnant, in their home in Frederick on Aug. 13, 2018, after she returned from a business trip.

He then drove her body to his job site and disposed of it. Watts also suffocated his two daughters, 4-year-old Bella and 3-year-old Celeste, and hid their bodies in oil drums.

“I am a new man, I am not the person who committed those horrible acts. 2 Corinthians 5:17 says ‘If any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.’ That’s me. I’m a new creature,” Watts wrote.

Watts also wrote that it has been most challenging to give himself grace, despite his opinion that God has done so.

“I know that God does not see me as a sinner who killed his family; he sees me as His child. I have confessed my sins. I am forgiven. The hardest thing I have had to do was to forgive myself,” he wrote.

Watts’ alleged motive for the murders was to be with his mistress, Nichol Kessinger.

In a previous letter, he described her as a “harlot” and a “Jezebel.”

“She was just everything my wife wasn’t like with me. She was just nice, and not a control freak. We could make decisions together,” he wrote.
