The Holy Spirit A B Simpson Chapter 15 – All the Blessings of the Spirit, or the Holy Ghost in Ephesians I. THE SEALING OF THE SPIRIT. “In whom, after ye believed, ye were sealed with that Holy Spirit of promise, which is the earnest of our inheritance until the redemption of the purchased possession.” Ephesians 1:13-14. We have already spoken in a former chapter of the seal and earnest of the Spirit, and it is not necessary to enlarge upon them here. The seal is the mark of ownership, reality, certainty and resemblance, the earnest is the first installment and pledge of the full inheritance. The Holy Ghost, when He seals us, makes real and sure to us the blessings of our inheritance and stamps us with the image of Christ; and, as the earnest, He gives to us the promise and the pledge of all the fullness of our future heritage.
