U- Unveiling the Word

σφραγίζω carries profound significance in both practical and spiritual contexts. Originally denoting the physical act of sealing with a signet ring for authentication or security, it developed rich theological meaning in the New Testament. From sealing the Messiah’s tomb to the Spirit’s sealing of believers, this word expresses divine ownership and authentication. The early church saw it as a powerful symbol of God’s claim on His people and His guarantee of their salvation. Today, it continues to affirm our secure position in the Messiah and the Spirit’s authenticating work.
