Ephesians 5:12 in the King James Version (KJV) of the Bible reads, "For it is a shame even to speak of those things which are done of them in secret." This verse is part of a larger passage in which the Apostle Paul is exhorting the believers in Ephesus to walk in love and light, and to avoid participating in the unfruitful works of darkness.

The context of this verse is important in understanding its meaning and significance. In the preceding verses, Paul encourages the believers to imitate God and to walk in love, just as Christ loved us and gave Himself for us. He also warns against immorality, impurity, and greed, stating that those who engage in such behaviors have no inheritance in the kingdom of Christ and of God.

In verse 11, Paul urges the believers to have no fellowship with the unfruitful works of darkness, but rather to reprove them. This sets the stage for verse 12, where Paul emphasizes the shamefulness of even speaking about the sinful deeds that are done in secret. This highlights the idea that believers are to distance themselves not only from participating in sinful activities, but also from discussing or glorifying them in any way.

The theme of light and darkness is central to this passage and to the broader message of the book of Ephesians. Throughout the letter, Paul contrasts the old way of life characterized by darkness, deception, and immorality with the new way of life in Christ, which is marked by truth, righteousness, and light. Believers are called to live as children of light, exposing and dispelling the works of darkness through their words and actions.

The significance of Ephesians 5:12 lies in its call for believers to maintain a high standard of moral conduct and to guard their speech and thoughts. By underscoring the shamefulness of even speaking about the secret sins of others, Paul underscores the importance of maintaining purity and integrity in all areas of life. This verse also serves as a reminder that believers are called to be a light in the world, and to avoid becoming entangled in the darkness that surrounds them.

Symbolically, the reference to "those things which are done of them in secret" can also be seen as a warning against the hidden, unseen sins that can easily ensnare and entangle believers. It serves as a reminder that God sees all, including the secret sins that may be hidden from human eyes, and that believers are accountable for their actions, whether public or private.

In summary, Ephesians 5:12 is a powerful exhortation for believers to live as children of light, refraining from participating in or even speaking about the unfruitful works of darkness. It reinforces the theme of maintaining a high standard of moral conduct and integrity, and serves as a reminder of the spiritual battle between light and darkness. As believers strive to walk in love and imitate God, Ephesians 5:12 encourages them to uphold the values of truth, righteousness, and purity in all areas of life.
