Backsliders
Backsliding (Hebrew meshuvah, "turning back"; Greek apostasia) refers to the pattern of spiritual decline, unfaithfulness, and departure from God that recurs throughout Israel's history and is addressed repeatedly in the wisdom and prophetic literature. The verb shuv (turn/return) underlies both the diagnosis ("they have turned away") and the cure ("return to the LORD"). The prophets frequently deploy the image of Israel as an unfaithful spouse or wayward child who has abandoned her first love (Jer. 2:13–19; 3:22; Hos. 11:1–7; 14:4). Proverbs 14:14 states: "The backslider in heart will be filled with the fruit of his ways." The NT addresses the danger of spiritual regression: Hebrews warns against "drifting away" (Heb. 2:1), "falling away" (Heb. 6:6), and "shrinking back to destruction" (Heb. 10:39), and calls believers to hold fast their confession (Heb. 4:14; 10:23). Jesus' letters to the seven churches rebuke those who have "abandoned the love you had at first" (Rev. 2:4). Restoration for the backslider is a consistent divine promise: "Return, faithless Israel... I will not look on you in anger, for I am merciful" (Jer. 3:12).
