So your salvation is based on belief plus something else, a work that you do.
Friend, that isn't salvation.
Your salvation appears to be based on grace plus something else (belief).
And what's worse, in John 6:28-29 Jesus explicitly says that belief itself is a 'work', so apparently you believe in works-based salvation.
Given this:
"Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him will I also deny before my Father which is in heaven." -- Matthew 10:32-33
and this:
"That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved." -- Romans 10:9
Were these people saved?
"Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue" -- John 12:42
