Christians are called to live differently in a world moving away from God, much like swimming against a rip current. Two kingdoms are in collision - the kingdom of self-rule versus God's kingdom of surrender and holiness. Believers are specifically built to resist cultural currents that contradict biblical truth, shine as witnesses through their lives, and actively advance God's kingdom. This requires paying closer attention to God's word to avoid the subtle danger of spiritual drift that happens through neglect rather than rebellion.
