The sermon on the mount is the constitution for living on earth when Christ is King. It is not church doctrine. See example below.
Matthew 6
14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Our forgiveness is based upon the shed blood of Jesus Christ, not forgiving others.
Matthew 6
14 For if ye forgive men their trespasses, your heavenly Father will also forgive you:
15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Our forgiveness is based upon the shed blood of Jesus Christ, not forgiving others.
Christ was sent to tell us about the kingdom of heaven and the sermon on the mount is the best of those instructions Christ gave for how we are to live with heaven as our true home.
Matt. 4:17 From that time on Jesus began to preach, “Repent, for the kingdom of heaven has come near.”
