" Does it make sense to say "I will never kill you by a flood, next time I will use fire? Just asking."
Ummm . . . actually, that's kind of what Peter said. LOL.
"For, according to their wish, this fact escapes their notice, that there were heavens from of old and an earth standing compactly out of water and in the midst of water by the word of God; 6 and by those [means] the world of that time suffered destruction when it was deluged with water. 7 But by the same word the heavens and the earth that are now are stored up for fire and are being reserved to the day of judgment and of destruction of the ungodly men." - 2 Peter 3:5-7, NWT
It just goes to show that the bible is an inconsistent book and its inconsistency is especially seen when comparing the OT with the NT which leads me to conclude that the NT is an unorthodox addition to the bible and christianity is actually a heretical offshoot from Judaeism. Here's an example that highlights how the NT contradicts the OT proving that the NT is not really part of the bible cannon but a later clumsy add-on:
"This is what Jehovah has said, your Repurchaser and the Former of you from the belly: “I, Jehovah, am doing everything, stretching out the heavens by myself, laying out the earth. Who was with me?" - Isaiah 44:24
Contrast this with Colossians 1:15-17:
"He is the image of the invisible God, the firstborn of all creation; 16 because by means of him all [other] things were created in the heavens and upon the earth, the things visible and the things invisible, no matter whether they are thrones or lordships or governments or authorities. All [other] things have been created through him and for him. 17 Also, he is before all [other] things and by means of him all [other] things were made to exist,"
There is a clear contradiction here. In the OT Jehovah says that he created the earth and stretched out the heavens by himself. In Colossians it says all this was done through - and hence, with - Jesus. So which was it - Jehovah alone? Or Jehovah with Jesus? Christianity does not mesh seemlessly with the OT and I suppose this is partly responsible for the development of the trinity doctrine to smooth over the inconsistencies produced by texts like the last two I highlight above.
Then there is the problem of the messianic prophecies, many of which, if one is truly honest and objective, don't read like prophecies at all but were clearly twisted by NT writers to make them seem like prophecies. Jesus failed to fulfill all the important and explicit Messianic prophecies in the OT so the NT writers resorted to twisting obscure OT texts that weren't written as Messianic prophecies to make them seem like they were, and portray Jesus as fulfilling them. And the major, explicit Messianic prophecies in the OT, are conveniently deffered to a future fulfillment in a "second coming". How convenient.
