Plenty of people believe they can live without God—including some former Christians who are now atheists. Part of this way of thinking may stem from religion, which puts forth multiple requirements to fulfill in order to please God. In the Old Testament, the people blocked themselves from God’s blessings through an attitude that indicated they thought they could obey the law through their own efforts, without His help. This mindset still exists today; it is called secular humanism, in which the world exalts the “self-made man.” However, anything good that happens to us is by God’s grace and mercy, not by our own performance. Failure to acknowledge this is sheer arrogance. To achieve any level of success at all, we need God.
