What? You think God failed? Perhaps you may be overlooking the fact that God didn't see it as His word so didn't preserve it? Not much faith in God there.
>>he words of God Himself that says that His word would not be found on the earth.<<
There we see the lack of knowledge of scripture that the Mormons and others have. You used Amos 8 as your example. But you neglect to include who God is talking to in that chapter.
Amos 8:2...Then the Lord said to me, The time is ripe for my people Israel; I will spare them no longer.
Just as He warned the people of Israel as a whole have wondered the world over but have not found the word of the Lord as it applies to the Messiah. God keeps His promises and His warnings.
>>Without them there would be no Bible.<<
Wow! Your lack of faith in God is showing. Did not He say that if the apostles kept silent like the Pharisees wanted the very stones would cry out?
Luke 19:40 And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.
God has always and will always keep His word StormPrepper. He preserved the word He wanted preserved. It has been available to all generations just as He promised. The fact that some don't see it like the Israelites, Mormons, and others is only a consequence of their own rebelliousness as spoken of in John 12.
