"In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise." Ephesians 1.13Lately, Edir has been talking a lot about the Spirit of Promise. And the verse above goes further, for it speaks of the seal of the Spirit of Promise. This seal is a guarantee of God's fulfillment of His promise. That is, seal is the title of property given by the Lord Jesus.
