How do we know the sealing of the Holy Spirit is true?

The sealing of the Holy Spirit is substantiated by biblical teachings, specifically in Ephesians 4:30, where the sealing is linked to the assurance of redemption. This doctrine is further supported by the believer's experiential knowledge of God's love and grace in their lives. The internal witness of the Holy Spirit confirms that once sealed, a believer enjoys an unbreakable relationship with God.

Moreover, the permanence of this sealing underscores God's faithfulness to His covenant, where He has committed to keep those whom He has called. Believers find solace in the truth that even in their darkest hours, the Spirit's presence remains as a source of hope and strength. This assurance, coupled with the doctrinal teachings of Scripture, supports the reality that the sealing of the Holy Spirit is not only a truth but a profound blessing that sustains the believer until the final day of redemption.
