***It’s not an insult; it’s what we believe.***
And it is not an insult when I say I am saved, through Jesus Christ, without your church.
In the beginning was the Word...
What must I do to be saved, said the Jailer. Believe in the Lord Jesus Christ and you shall be saved.
Good enough for me.
No it's not. Insults come from ego. Don't let other people's beliefs insult you. If you think they are wrong, pray for them, and thank God.
