Brief Overview of σαπρός (Strong’s G4550: sapros)

Strong’s G4550: An adjective denoting that which is rotten, putrid, or corrupted by age. In New Testament usage, it describes both physical decay and moral corruption, particularly in Jesus’ teachings about fruit-bearing and speech, emphasizing the connection between inner character and outward manifestation.

U- Unveiling the Word

Σαπρός primarily describes something that has deteriorated beyond usefulness, whether physically rotten or morally corrupt. In the New Testament, Jesus uses this word powerfully in His teachings about good and bad fruit (Matthew 7:17-18) and corrupt speech (Ephesians 4:29). The early church understood this term as more than just physical decay; it represented the spiritual deterioration that occurs when one lives apart from God’s transforming grace. Today, σαπρός reminds us that our words and actions reflect our spiritual condition, challenging believers to examine the “fruit” of their lives.
