“I do not want to have anything to do with it!”
“I have my own problems”!
With these reasons most people reject to give donations. Yet, even speakers and other people who have nothing to do with the Christian faith, who only have the observations of this world, even they have discovered the mystery that by giving they in the end have more rather than less. It is not only about money, it is also about giving time, e.g. to young or to old people, and to help where we can.
We can never “earn” anything in heaven, but once we understand how overwhelming is the great free gift that God gives us freely in his mercy, then in thankfulness we want pass on as many blessings as possible to others.
