How does being sealed by the Holy Spirit affect a believer?

Ephesians 1:13-14 explains that believers are sealed with the Holy Spirit as a guarantee of their inheritance until their ultimate redemption. This sealing signifies that God has marked His people as His possession, ensuring their security and preserving their faith. This means that believers cannot lose their salvation or be separated from God’s love. The Holy Spirit acts as the earnest or down payment regarding the spiritual blessings that await us. This divine seal signifies both God’s commitment to us and the transformative work He performs in our lives, confirming that we are safely kept by His power.
