(SEE-ling of the Holy Spirit)
The Definition
Merriam-Webster: Seal — a mark of ownership, authenticity, or security.
FTG Expanded Explanation: The sealing of the Holy Spirit is God's act of marking every believer as His own at the moment of salvation. The Holy Spirit Himself is the divine seal, guaranteeing the believer's salvation and future inheritance until the day of redemption. This seal signifies God's ownership, security, and promise that He will complete the work He has begun. Because believers are sealed by God, they can have assurance that their salvation rests on His faithfulness rather than their own performance.

Ephesians 4:30 – "Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption."
2 Corinthians 1:21–22 – "Now He who establishes us with you in Christ and anointed us is God, who also sealed us and gave us the Spirit in our hearts as a pledge.”
Used in an Everyday Conversation
