Atheist Morality, a Biblical Perspective

Everyone has an innate sense of morality, and we don't need religion to tell us what it is. Christians should agree with me, if they read their Bible. (My italics below)

Matthew 7:12
"So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets."

Romans 2:14-15
"(Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law, since they show that the requirements of the law are written on their hearts, their consciences also bearing witness, and their thoughts now accusing, now even defending them.)"

Morality can be summed up by the golden rule, can be found within our own hearts, and doesn't require religion or belief in God. QED

My only point of difference is, of course, that these laws were not written on our hearts by God. Their innate nature should not be contested.
