I love your post. Giving certainly provokes blessing in return. Infact God promised that in His word.
However, God is more pleased, more honoured when we give, not for the sake of receiving, but because we love Him and others. If we give only because we expect to receive, we have done nothing noble, because everyone does that.
God wants to bring us to the point where all our resources are used to honour Him. Then we will be very happy to give them up to others when the need arises.
My point is that: God blesses us when we give our resources to people. But He is more pleased when we give our heart and love to them.
