If that person is not saved, how did their name get in the Book of Life?
Why did Jesus this in Rev. 3:5?
"He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
There are some that "did run well" as Paul said! But in the end they "fell from grace" as Paul also said![/QUOTE
Again, that passage does not indicate that one can lose their salvation by their own means. You have read it in conjunction with the text as a whole and other scripture.
Paul in Galatians is addressing those that believe that the law justifies them before God.
Mark my words! I, Paul, tell you that if you let yourselves be circumcised, Christ will be of no value to you at all. Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law. You who are trying to be justified by the law have been alienated from Christ; you have fallen away from grace.
Galatians 5:2-4
Also Jesus made this statement:
This is the will of Him who sent Me, that of all that He has given Me I lose nothing, but raise it up on the last day
John 6: 39
To reiterate this, the writer or Hebrews says:
so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil, where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek.
Hebrews 6: 18-20
God does not lie nor renege on His word. Once secured(Before the foundation of the world) one is always secure.
