God does not need for us to make judgements, no matter the what, on His behalf. All judgement has been reserved for Christ, and Christ alone. If God were to 'need' our help He would not be much of a God. God has no needs, period. He transcends our ability to even begin to understand Him.
God, however, desires that we love Him. And, with that, He desires we love all others in the same manner as we love ourselves. He does not call us to love those who love us, he does not call us to love a people of our own kind. That which we are called to do, if we truly follow Him, to love the worst of the worst and to do so unconditionally, without reservation; no ifs, ands, or buts.
God does not want a child in the slums of Rio de Janerio to go hungry. He does not want a family, stricken apart by the earthquake, in Haiti to suffer. He does not want the mother of three, four, five any number, small children to feel, and believe in the depths of her heart, there is no hope for her, no one who cares. God does not want those warehoused in nursing homes across the USA to feel the pain of abandonment and loneliness. He does not wish for a fifth grader in Oakland to hustle on the streets to help feed his family. God desires that all people receive food from His bounty, His fields, His gardens, His cows, His world in a fair and equitable manner so that no one is left out. He desires the wars and hatemongering amongst religions cease. He desires that we love our enemies just as we love ourselves. Somehow, what He would desire for us as we allow the Holy Spirit to move through us gets lsot in the shuffle.
"What? I hvae to give up which car! Wait a minute, I earned this, what do you mean that I am to take only that which is necessary for me and mine to live and the rest goes to the poor! Surely you joke!" Who wants to hear the pure truth that we are to lead simple lives and nothing more. Certainly no one wants to hear that we are meant to keep onl the money necessary for ourselves and our families. Anything beyond that is to be given to the poor. If we cannot detach ourselves from the trappings of this life there is no possible way to prepare for a life with Him. Only when we detach ourselves from the me, myself and I can we even begin to follow Him.
