Persoally I don't think God intended for us to build His kingdom on Earth. He intended for us to BE His kingdom on Earth. Whenever we presume to dictate what God wants of us, we will almost always get it wrong. Whenever we yield ourselves to God and do his bidding, a whole lot more gets accomplished.
I think that is why the so-called government poverty programs etc., all with good intentions to make things better for people, have had such mixed results, too often negative results. Whenever we think us humans are clever enough or compassionate enough or smart enough to take God's place, we are pretty sure to screw it up.
I do believe the Kingdom of God is now and we get glimpses of it every now and then. It is a real blessing when we do. And we also continue to witness and reap the wages of sin, both ours and those of others, some who lived long ago. We are all still a work in progress.
I think we need a whole lot more focus on letting God be God and letting the decision making come from God down. Every time we people think we can cut God out of the equation or take His place, we will have regrets.
i don't think we stop being charitable when we leave the church...i don't think God's kingdom ends at the gvt's door or when in the public square...
i've never witness God handing bread and water to humans in need, but i have witnessed human beings helping other human beings, and i view this as the hand of God, or God being within them....after all, God is
Goo
d and doing any Good, IS the will of God.... doing and thinking Evil is of the Devil....
so, i see no harm, in doing Good, in all aspects of life, and i see it as supporting God's will.
