Is being good good enough for God‭?

Matthew‭ ‬21:33-46 As we look around the world it seems obvious that Christians do not have a monopoly on doing good.‭ ‬In many cases Christians are put to shame by the superior kindness and integrity of those who don‭’‬t share their faith.‭ ‬Is it not then arrogant to suggest that people have to be Christian to be acceptable to God‭?
