There are two simple, but opposite, philosophies of life.
The first explains that every person is conceived as morally perverted and sinful. No amount of nurturing, training, or money improves the thoughts, motives, or intentions of the person. That moral corruption alienates everyone from God and makes all pursuits selfish. A person’s only hope is to be reborn by the Spirit of God through faith in Jesus Christ.
The second philosophy teaches that everyone is born as a blank slate. Environment, nurture, and social and economic structures influence and improve the thoughts, motives, and intentions of the person. Morality is dictated by the social structure and support of family, friends, and government. Basically, humanity is good, and personal destiny is ultimately up to the individual.
The first is Christianity; the second is humanistic atheism.
Behold, I was brought forth in iniquity, and in sin my mother conceived me. There is none righteous, no, not one … there is none who does good, no, not one. The heart is deceitful above all things, and desperately wicked (Psalm 51:5; Romans 3:10, 12; Jeremiah 17:9).
Where does your philosophy of life come from? The Bible or humanism?
