Church Giving to the Poor The Bible and Jesus clearly speak of giving money to the church and in turn fellow Christians should give up all they have and look out for one another.

So my question is why does this not happen now a day. I know many in my Church who tithes a lot (I do it myself) but it saddens me that my same Church would probably not give me a grant of money If I suddenly lost my Job or something.

Why has this has happened? 

From the days of Paul, Jesus and Timothy to now the church now (was outside of the world) and now it appears (the world is in the church).
There is a fallacy in your argument.  You said:

You are conflating two bits of Scripture.


Jesus told the Rich Young Ruler (here from Mark)


  21 Looking at him, Jesus felt a love for him and said to him, “One thing you lack: go and sell all you possess and give to the poor, and you will have treasure in heaven; and come, follow Me.” 

In Acts 4, the early church was clearly looking out for each other


  32 All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had. 33 With great power the apostles continued to testify to the resurrection of the Lord Jesus. And God’s grace was so powerfully at work in them all 34 that there were no needy persons among them. For from time to time those who owned land or houses sold them, brought the money from the sales 35 and put it at the apostles’ feet, and it was distributed to anyone who had need.



The conflation being made here is that Jesus told the church to live as one.  This communal form of living together arose from a belief that Jesus would return immediately.  (Indeed, as a side point, 2 Thessalonians is written to just such a community)

The possessions that are to be "sold and given to the poor" are given to just that - the poor.  Losing your job may or may not qualify you for that. Indeed, as a pastor, I have specifically hired people in the church who had temporarily lost jobs, and yes, I usually pushed the benevolent fund to church members first, but the point is - it is the poor, not the community that the intended beneficiary.
