Why is it important for Christians to avoid complacency?

It is crucial for Christians to avoid complacency because it can result in spiritual decline and alienation from the gospel of grace. Hebrews 10:35 warns against casting away confidence in Christ, emphasizing that maintaining a bold faith has a great recompense of reward. The danger of complacency is that it can cause individuals to drift away from the deep commitment required to follow Christ, potentially leading them towards apostasy. External trials are significant, but complacency may be more detrimental, as it subtly lulls believers into a state where they may neglect their relationship with God and the church community (Hebrews 10:25). Therefore, Christians are called to encourage one another to remain steadfast and alert.
