Nice try but that is not what the verse says. But Mormons twist the Bible so much that they do not understand that.
Christians are to bless those that persecute us (curse us) for our faith. It says NOTHING about blessing heretics.
Nowhere does it say we are to bless those who preach a false gospel. Quite the opposite, we are to contend for Christianity, we are NOT to bless those that bring false doctrine and we are to CUT ASUNDER those who ‘seek to be equal’ to Christians while teaching false doctrines (like Mormonism).
If you understood the Bible you would know that!
I've been blessed to attend a Christian Church that actually "taught" the Word of God.
It always amazes me...the folks that don't understand Scripture.
