What does it mean to be sealed by the Holy Spirit?

The sealing of the Holy Spirit is a biblical concept representing God's promise and assurance to believers. According to Ephesians 1:13-14, upon believing in Christ, we are sealed with the Holy Spirit of promise, which is a guarantee of our inheritance until the redemption of God's own possession. This seal indicates that we belong to God, and it serves as protection against judgment. The Holy Spirit also equips us and leads us, helping us to live in a manner that reflects our salvation. Essentially, being sealed signifies that we have been marked by God's grace and are preserved in our faith.
