What does the Bible say about being sealed in Christ?

The concept of being sealed in Christ is profoundly significant in the New Testament. It signifies God's stamp of approval and ownership over His people. Scripture states that after hearing the word of truth and believing, believers are sealed with the Holy Spirit of promise. This seal represents a pledge of their inheritance until the final redemption. It assures believers of their position in Christ, indicating they are not strangers but fellow citizens of God's household, built upon Jesus Christ, the chief cornerstone. This sealing is not based on our merit, but solely on God's grace and mercy.
