Jude 1:5—“I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt, afterward destroyed them that believed not.”

Jude reminds believers of a sobering historical lesson from Israel’s wilderness journey. Though God graciously delivered the Israelites from Egyptian bondage through mighty signs and wonders, many later perished in unbelief because they refused to trust and obey Him. Their outward deliverance did not guarantee their spiritual transformation and faithfulness. Their spatial deliverance did not equal spiritual conversion. 

The phrase “I will therefore put you in remembrance” reveals the necessity of continual spiritual reminders. God’s people are often forgetful. Familiarity with biblical truth can lead to carelessness unless the heart remains humble and watchful. Jude’s warning confronts people’s tendency toward spiritual complacency. It is entirely possible to sit in a pew, speak the language of faith, and look back on a past religious experience, while currently harbouring an unbelieving, rebellious heart. 

This verse also teaches both the greatness of God’s saving mercy and the seriousness of unbelief. The same Lord who delivered Israel also judged those who persisted in rebellion. God’s requirement of holiness in His people is never diminished by the blessings Hs senHis grace. Privileges, experiences, and outward association with God’s people cannot replace genuine faith and perseverance.

Believers must guard against complacency. They can participate outwardly in Christian activities while harbouring an unbelieving heart. The Christian life requires continual trust in Christ, submission to His Word, and perseverance in holiness.

This verse calls us to examine ourselves carefully. Let us not merely remember God’s past mercies intellectually, but respond to them with enduring faith, reverence, and obedience unto the end.
