So being baptized 'in Jesus name' (in of itself) is supposed to be a magical formula for salvation? Those who were baptized in the name of the Father, Son and Holy Spirit is the wrong formula and people who are not baptized by the specific formula 'in Jesus name' will not be saved according to you?
So, if you have any doubt about whether or not you have these things, it is a good step to take.
I have noticed in my conversations with people that most who have not been baptized in His name, also deny the literal rendering of 1 John 3:9, 5:18. I would say that this is because in their own experience, their sins are not in remission.
