18. Hearken. A recurring theme in Deuteronomy. It stresses that there is no neutrality in God’s army (Matt. 12:30). The church today needs to pray constantly for divine power to maintain absolute loyalty. Note the apostle Peter’s exhortation for these last days (2 Peter 3:17, 18), Jude’s words of caution (Jude 17-25), and the message of Christ Himself on the Mount of Olives (Matt. 24:11-13).
