When he looked up he saw some wealthy people putting their offerings into the treasury and he noticed a poor widow putting in two small coins. He said, "I tell you truly, this poor widow put in more than all the rest; for those others have all made offerings from their surplus wealth, but she, from her poverty, has offered her whole livelihood." (Lk 21:1-4)
Every religion gives opportunities to its followers to give offerings. Revelation is the means through which God communicates with the people. Offerings and sacrifices are the means through which people approach God. God is the creator of all things and hence everything belongs to God. Everything should go back to God. Offering is a way through which people live this aspect of their faith.
This is the reason why Jesus permits offerings and makes comment on it. He watches people making offerings to God. Rich people make their offering into the treasury. Probably they were putting into the treasury their tithes. This could have been a sizable amount for a rich person. The rich person is happy and proud to give his tithe to God.
Jesus makes his comment on the poor widow who put in all what she had for her living. She lived out her faith: everything is a gift of God and hence everything belong to God. Her approach to God was not partial or limited rather she offered everything to God. She was totally submitted to God and surrendered to God Her faith was lived out to the full.
