On Christiansity..
The offer of eternal life is based on belief and repentance and not on how you live your life. To me this is totally wrong...
Good people who have lived good lives perish because of a lack of belief. People who have lived bad lives and hurt people, sometimes in the worst ways can be saved?
No thanks, I'll pass up that invitation.
The gift of eternal life is based on how you live your life. For now, since Jesus' resurrection, eternal life can only be gained by believing God's word to us (the Bible) and having faith in God's anointed saviour for mankind - Jesus. Christians will gain immortality (and therefore eternal life) when they are resurrected in the "first resurrection". They will be reigning with Jesus over the rest of mankind, those still living when Jesus returns to establish God's kingdom, and the rest of the dead who will be resurrected in the second resurrection. God has allowed 1,000 years for those to be restored to perfection, and a final test at the end. Satan is bound up at the start of that 1,000 years and he is released at the end to test mankind again. Those that remain faithful and obedient will gain eternal life at the end of the 1,000 years; those that are unfaithful and side with Satan will perish (the "second death") along with Satan and his demons:
Revelation 20:1-2 WEB
(1) I saw an angel coming down out of heaven, having the key of the abyss and a great chain in his hand.
(2) He seized the dragon, the old serpent, which is the devil and Satan, who deceives the whole inhabited earth, and bound him for a thousand years,
Revelation 20:4-8 WEB
(4) I saw thrones, and they sat on them, and judgment was given to them. I saw the souls of those who had been beheaded for the testimony of Jesus, and for the word of God, and such as didn’t worship the beast nor his image, and didn’t receive the mark on their forehead and on their hand. They lived and reigned with Christ for a thousand years. (5) The rest of the dead didn’t live until the thousand years were finished.
This is the first resurrection. (6) Blessed and holy is he who has part in the first resurrection. Over these, the second death has no power, but they will be priests of God and of Christ, and will reign with him one thousand years.
(7) And after the thousand years, Satan will be released from his prison,
(8) and he will come out to deceive the nations which are in the four corners of the earth, Gog and Magog, to gather them together to the war; the number of whom is as the sand of the sea.
Revelation 20:12 WEB
(12) ... The dead were judged out of the things which were written in the books, according to their works.
Jesus said, John 12:48-50 WEB
(48) He who rejects me, and doesn’t receive my sayings, has one who judges him. The word that I spoke, the same will judge him in the last day.
(49) For I spoke not from myself, but the Father who sent me, he gave me a commandment, what I should say, and what I should speak.
(50) I know that his commandment is eternal life. The things therefore which I speak, even as the Father has said to me, so I speak.”
Revelation 21:6-8 WEB
(6) He said to me, “I have become the Alpha and the Omega, the Beginning and the End. I will give freely to him who is thirsty from the spring of the water of life.
(7) He who overcomes, I will give him these things. I will be his God, and he will be my son.
(8) But for the cowardly, unbelieving, sinners, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars, their part is in the lake that burns with fire and sulfur, which is the second death.”
