The issue here isn't money or what we do for reward. The person who quietly gives $500.00 does so because the Holy Spirit asks them to and they do so will a joyful obident heart. The other gives $500.00 in order to prove to others that he has money, is more generous, is a better Christian. All things not from God.
We only need to do what God asks of us, no more, no less.
Personal example. For some reason I felt compelled to go to 7/11 for a slurpy. Now this isn't something I do on regular basis, it is rare. When I was leaving a boy came up to me and asked for changed so he could get gas for a car that wasn't there. I was compelled to give him a certain amount, no more no less, so he'd have enough to get where he needed to. I did so because God asked me to, not because I want a reward in heaven.
Jesus calls us to be servants to each other and help those in need. Not openly showing off because we are more pious then those arround us because the more pious are those unsung heros who listen to God and act quietly just as he does.
You have an issue with giving money to the Church. Many do and this I understand. But how will the church pay the mortgage, maintain the building, fix the plumbing, pay the pastors, reach out to the community and support those who give their lives to missions if no one gives. Some are called to give of their money, some are called to give of their time, others are called to give in kind, and some like myself are provided with a creative answer to support and give. God will let each of his children know what is appropriate and what is not. If you give and then are upset because your short cash or your upset because you didn't get the attention you wanted or you have regrets then it was not what God asked you to do.
God is clear in the Bible about the consequenses of all our actions. Some consequenses are bad, others are good. He lets us know ahead of time so there will be no surprises on judgement day. He's not trying to intice us to act a certain way for a reward, that is just the consequence of certain actions. Those that do just for reward, whether or not on earth or in heaven do so for selfish reasons and the consequence of that is clear as well.
Just a thought: Selfishness is the original sin and the basis for all sin. Think about it....
