Also, For man to experience absolute Salvation, He/She must be able to overcome Flesh, Sin, The World Etc.
7He who overcomes shall inherit all things, and I will be his God and he shall be My son. 8But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death. Revelation 21:7-8 NKJV
