If we, or for that matter any of us are christians, there is no need to raise our voices....
It is not to us to judge what someone should give. The bible says, if your righthand gives something, don't let your lefthand know. Each of us should share what they could. Some can give more than others. I don't think Jesus wanted us to sell everything we have and become poor people. In the chapter that he is talking to the rich young man, he saw that this young man was relying more on gold than God..even when he really wanted to live according to the bible.
Don't be eager to judge other people, lay low, take your own actions, your own words in consideration. Everyone is trusted with certain qualities, capacities, take responsibility for those, for that is what you are asked to do. And if there is something that needs to be said about another, do it mildly, for we need to construct eachother....
