Salvation

 A person who has establish true salvation can lose it as easily and as quickly as they obtained it. In the letter written named Hebrews. which is written to many churches throughout the land (meaning it is written to the saved not the lost) There is a Key writing here that Paul is telling the Church (Bride of Christ) Hebrews 6:4-6 4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit,
5 and have tasted the good word of God and the powers of the age to come, ( Does this sound like Saved people? ) Now note the very start of verse 6. If they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame ( A person has to first have what is needed in order to Fall away from it) This passage begs the question, “How can one be ‘enlightened’ and fall away?” It is speaking of someone losing his salvation. 1 Timothy 4:1 “The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.” ( Again another letter is written to the Church (The Saved) Rev. 3 shows that a person name can be taken out of the book of life as well as it went in it at one time. Revelation 3:5 “He who overcomes will, like them, be dressed in white. I will never blot out his name from the book of life, but will acknowledge his name before my Father and his angels.”
Revelation “And if anyone takes words away from this book of prophecy, God will take away from him his share in the tree of life and in the holy city, which are described in this book.”
