Apparently jesus raised the dead with the help of god. And the many stories of blind able to see, lame able to walk, food to feed thousands from little, etc. are "miracolous" stories of god's power. So why not have an amputee grow limbs? This ought to be an easy feat from an all powerful entity.
I never made Christianity a condition of belief for God; that's something you are introducing on your own. But as long as you brought it up, do you believe in God because of the alleged miracles of Christ? Apparently not, because you are hoping for an amputee miracle to convince you. You do, however, feel free to use the Bible miracles as a reason to expect that God should do more of the same today, only of a different flavor, perhaps. In-other-words, you don't accept the bible trash as proof of God, but still use it as a reason to expect that God should be perfectly willing to do more of the same. You reject the miracles, but expect God to perform more of the miracles you reject before you will believe.
First, in theory, even if the Jesus miracles are true, there's nothing to say that God has to heal amputees. So God could still exist in the absence of such a healing.
More importantly, I never said that one should have to consider any alleged Bible miracles in any "proof" of God. If you want to accept those Jesus miracles as true, then that's your prerogative, and you already have your proof. However, if you reject them as false, then they make a poor foundation for argument, for or against God. (Unless you are talking about the
Christian God, I suppose)
Really, I finish that thought with, I don't know why you think raising the dead and healing the blind to be any less amazing than growing limbs. Further, a person can find any number of "miracles" that God has yet to perform, and say, "See, we can't prove God yet, because that miracle as not yet occurred in the name of God." Had it been the case that, in the NT, an amputee had grown limbs, you would have asked for a liver or a spleen.
Which is it? Do you believe in the Christ miracles as your proof of God? and if not, then I would ask, don't use them as a reason to expect God to provide you with more of the same, to satisfy your penchant for limbs.
