“God has a firm loving grip on the believer, and no outside force can separate the believer from God and God’s love. A believer cannot lose his or her salvation as one might lose one’s glasses. But by willful rebellion there is the possibility of apostasy, of making shipwreck of one’s faith. The Good News, then, is that one cannot lose or misplace one’s salvation or simply wander away by accident. Indeed, only by an enormous willful effort could one throw it away. Such is the loving grasp God has on his children.”
