The Bible records in Hebrews Chapter 9, that it is appointed unto men to die once and then the judgment. The operative word is ‘Once’.
All our us will die one day, unless the Lord returns in his appointed time, wherein those who believe in Jesus Christ to be Lord and Savior will be caught up (raptured) to be with Him.

As I said, the operative word in that statement is ‘Once’. But the Bible also talks about a second death, which is reserved for those who have not accepted Jesus Christ as Lord and Savior and believed in Him. It must be recognized that while the first death is appointed, the second death is a verdict upon judgment.

The question then is – Not if we will die, but when we will die (first death),  will you and I have to face second death?
He that believes in Jesus Christ shall not perish (face second death), but have eternal life (John 3:16).

Hebrews 9:23-28 (KJV)
23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these.
24 For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
25 Nor yet that he should offer himself often, as the high priest entereth into the holy place every year with blood of others;
26 For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.
27 And as it is appointed unto men once to die, but after this the judgment:
28 So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.

Revelation 21:7-9 (KJV)
7 He that overcometh shall inherit all things; and I will be his God, and he shall be my son.|
8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
