Let`s you do more good for people than christians do by just sitting there and waiting for jesus, have you then disproven their belief? Yes, let`s say youre just open-minded about god and jesus or an atheist even, but you do more than christians do in terms of good for others, is their belief flawed then since it makes them more passive?
I think the premise is based upon your narrow experiences with Christians.
Most Christians aren't "sitting there and waiting for Jesus". In fact our Scriptures directly teach against doing this, and Christian moral teaching for the last two thousand years has been to be pro-active in helping the poor, the hungry, and the needy.
The fact that many Christians today are at odds with historic Christian teaching isn't evidence against Christianity. It is evidence of something amiss and deeply wrong about the way Christianity is often being taught and practiced today, but not against Christianity itself. This is far closer to an example of G.K. Chesterton's statement that "
The Christian ideal has not been tried and found wanting. It has been found difficult; and left untried."
At the end of the day Christianity still says, as Matthew 25 does, that how we treat other people--especially the "least of these"--is how we shall be judged by Christ in the end. And St. John in his first epistle still says that if anyone claims they love God but hates their brother such a person is a liar. Because it is impossible to say you love God and hate your fellow human being made in God's image. Loving our neighbor is
how we love God.
In the Lutheran tradition--and I am Lutheran--it is made expressly clear that a good work that is done "for God", but does not in anyway benefit our neighbor, can't be called a "good work" at all. Because God doesn't need our good works, our neighbor does. Our neighbor is the one who is hungry, thirsty, naked, alone, imprisoned, and sick.
