How do I know this? For various reasons. Does it make sense to you that God would kill them and then torture them more after they drowned? No, it does not make sense to me. The deaths of those persons was punishment enough, God needed to rid the earth of these bad people. I know this: there are requirements meant for salvation. It goes beyond being nice, polite, and friendly, even good families. If I am alive when the 'end' comes, I believe I will see exactly who God approves of if I live long enough. Faith, and ideas lead to actions. If I thought that any other religion was teaching the truth as I understand the truth to be, I would feel free to join them. But I don't.<quoted text>
Why not answer my question about a God who will kill 99% of the world because they don't call themselves Jehovah's Witnesses? Good Christian people who have given their whole lives to the Lord, how is that a loving God?
And how do you know that when those who died in Noah's day are not suffering some place? You DON'T KNOW, I DON'T KNOW, NO ONE KNOWS but God himself.
Jesus said at John 17:3 - This means everlasting life -- their taking in knowledge of you, the only true God, and of the one who you sent forth.
Therefore, taking in knowledge of God is essential to everlasting life.
