You are saved Only Once!
Correct!
Scripture says that we cannot be re-saved.Hebrews 6:4 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
5 And have tasted the good word of God, and the powers of the world to come,
6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
I think we are actually in agreement on that. The question now is whether or not you can know you are saved.
