From Karen Jobes's commentary on I John, reflecting on I John 5:5:
Without faith in Christ, no one is able to face down the evil, the hopelessness, and the self-defeat that this world presses on us day by day. There may be many self-help gurus who write and speak about how to live a better life, and some of what they say may be helpful and worthwhile. But what is of the world cannot give us victory over the world. Without trust in Christ, who came into the world from God, even the most successful life is swallowed up in the defeat of death.
I can't help but think of the many ways we as Christians unconsciously try to use worldly ways to overcome the very world we live in. The political process, more education, more social justice, more financial security. And yet, ultimately, none of those things can overcome the world. They may offer a poorly placed band-aid, but ultimately, they cannot do what only Christ can do.
