13In Him, you also, after listening to the message of truth, the gospel of your salvationhaving also believed, you were sealed in Him with the Holy Spirit of promise, 14who is given as a pledge of our inheritance, with a view to the redemption of Gods own possession, to the praise of His glory. Ephesians 1:13-14 NASB
The Greek for pledge, ἀρραβών, conveys the following meaning:
728 /arrhabṓn ("down-payment pledge") is the regular term in NT times for "earnest-money," i.e. advance-payment that guarantees the rest will be given. 728 (arrhabṓn) then represents full security backed by the purchaser who supplies sufficient proof they will fulfill the entire pledge (promise).

The words....you were sealed....is the greek verb ἐσφραγίσθητε
It conveys the meaning of: 4972 /sphragízō ("to seal") signifies ownership and the full security carried by the backing (full authority) of the owner. "Sealing" in the ancient world served as a "legal signature" which guaranteed the promise (contents) of what was sealed.
It is an aorist, indicative, passive verb.
The passive voice in Koine Greek means the following:
In general it can be said that in the passive voice the subject is acted upon or receives the action of the verb. No volition-nor even necessarily awareness of the action- is implied on the part of the subject (Daniel B. Wallace, Greek Grammar Beyond the Basis, p431).
We had no part in our sealing. This was done by God.
My that all sounds very impressive until one considers how long Revisionist scholars were united in their agreement over the petros, petras nonsense.
