Vanderhoven7, people often only give gifts to people who have acted in certain ways to them. Though no one earned the gifts, the givers often choose to give only to those whom he/she has a favorable opinion of - while at the same time believing that those people did no earn the gifts. Parts of the Bible give the impression of teaching that God acts similarly. The Letter to the Hebrews teaches that faith without words is dead, and it teaches that those who have faith will have works which accompany the faith.
Part of the Bible are figuratively 'at war' with other parts of the Bible, and even parts of the NT are figuratively 'at war' with other parts of the NT. This shows that the Bible is entirely the book of humans and not the book of God. Some of the human writers of the Bible were disagreeing with some other human writers of the Bible, and they were trying to contradict the words of each other. Even some individual books of the Bible contradict themselves, and thus show evidence of being edited to include an opposing view. In other words, some people dared to add words (stating an opposing message) to existing books of the Bible, even to words attributed to Jesus! That is despite warnings like that found in Revelation 22:18-19!
Though parts of the NT say that the salvation of Christians are assured (provided they believe in Christ as their savior), other parts of the NT say it is not guaranteed, but that Christians must also act in a godly and holy manner in order to be saved.
In the story about Noah's Ark, Noah and his family had to build the Ark and enter it in order to be saved. Likewise according to the story, anyone else who wanted to be saved had to exercise faith by entering the Ark. According to the Gospel attributed as being according to Matthew, when the son of man comes, it will be as in the days of Noah. That same gospel claims that Jesus told his disciples that they need to keep on the watch for his return. If they were already eternally saved, why were told they have to keep on the watch?
2 Peter chapter 2 speaks of those who "escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ but who later became overcome by that which they had escaped from. Verse 21 (NASB Updated) says that for those who were overcome that "it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them."
2 Peter chapter 3 makes reference to the flood of Noah's day of the day of the Lord (though the 1984 NWT says "Jehovah's day") coming as a thief and that as a result Christians are be a people who are "in holy conduct and godliness" (see verse 11) and be "looking for new heavens and a new earth, in which righteousness dwells" (see verse 13). Verses 14-15 (NASB Updated) say "Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless, and regard the patience of our Lord as salvation ...".
Revelation 22:12-15 claims that Jesus says he will give a reward to each one as his work is. The book says that Jesus says that those who wash their robes will receive access to the trees of life and entrance into the city. Revelation also says that Jesus says that those outside of the city are "the dogs", those who practice spiritism, the fornicators, the murders, the idolaters, "and everyone liking and carrying on a lie". Verse 19 says there are some (those who take away from the words of the book of Revelation) whom "God will take away his part from the tree of life and from the holy city" thus indicating is possible for some Christians to loose the prospect of salvation.
