Then God doesn't care about the goodness and decency of an atheist, a buddhist, etc. And if that is the message you are telling me, then there is no point to being a good person. There is no point of fighting on behalf of the oppressed, as America did, in WWII. The only purpose of fighting the Japanese, and beating back the Nazi's should have been so that we could bring more people to christ...is that what your saying? Should America be sending food and aid to heathens in Haiti? Should America be helping out muslims in disaster relief fallowing a natural disaster, unless it is to bring them to Christ? Is a person's only value to you, there potential to become a convert? They have no humanity beyond that?
You have an old testament my_adonai, and you are to be as obsessed with its obsessions, as you are with the new testament's. And the Old Testament's preoccupation is fighting evil, championing the good, and making a more ethical existence, during this lifetime.
And unless you think Christians alone can make this lifetime a little better, a little less genocidal, with a little less starvation, a little less torture, etc, it is an unethical message to peddle, that a good God would demand goodness, unless one doesn't believe in his son. Then one's goodness is pointless. One might as well not care about not gossiping behind other people's back, destroying someone's dignity in public, sleeping with a coworker's wife, extorting an elderly couple that one was hired to help, raping a pre-pubcescent child, killing another human being because of their skin color, etc, etc, etc.
