I am pondering if there is something incomplete when the gospel is
presented to these people before they made decision to accept
Jesus.
Usually in the gospel presentation to non believers, they are
all told once they believe their sins will be cleansed, they don't
need pay penalty for sins as christ has paid for it on the
cross. They accept Jesus, they go heaven.
These potential christians are not told about what Jesus said in
the new testatment "Not all who called me Lord Lord will enter the
Kingdom of Heaven, but those who repent and do the will of
God".
Thus, they claim by believing and accepting Jesus they have free
passport to go heaven and don't care a thing about repentence and
treating others nice and kind.
They go around bashing people's religions and insulting them,
but Jesus said to win them over with love and sincerity. I think
they should take the initiates only to introduce christianity to
non christians, and then, when they are interested, just try to
explain and teach them about the Bible, not just bash and say your
religion is shit and false or whatever.
