Non-believers and Morality

Kessler talks about morality and religion as going hand in hand. People who are non-believers can have very high morals and act very kind towards others. This does not mean that this person is a child of God however. In the Bible it says that good deeds and being a good person alone will not allow you into the Kingdom of Heaven but by faith, and faith alone. Missionary work is so important in reaching those who are non-believers and teaching them about faith and how their morals are good, yes, but they by themselves are not enough. "RELIGIONS" can teach people that being a good person is all that you need, but true Christians know that is not the case.
