Ephesians 1:11-14
God’s people are God’s ‘saints’ (verse 1), God’s heritage (verse 12), God’s possession (verse 14).
How did we become God’s people or possession? There can be no doubt about Paul’s reply. It was by the will of God. He destined us to be his sons according to the purpose of his will (verse 5); he has made known to us the mystery of his will according to his purpose (verse 9); and we have become God’s heritage according to the purpose of him who accomplishes all things according to the counsel of his will (verses 11–12).
And the assurance that God is thus active in the lives of his people is given through the Holy Spirit, who in verses 13 and 14 is given three designations—a ‘promise’, a ‘seal’ and a ‘guarantee’. First he is (literally) ‘the Spirit of the promise’ because God promised through the Old Testament prophets and through Jesus to send him (which he did on the Day of Pentecost) and God promises to give him today to everyone who repents and believes (which he does).
Secondly, the Holy Spirit is not only God’s ‘promise’, but also God’s ‘seal’. A seal is a mark of ownership and of authenticity. Cattle, and even slaves, were branded with a seal by their masters, in order to indicate to whom they belonged. But such seals were external, while God’s is in the heart. He puts his Spirit within his people in order to mark them as his own.
Thirdly, the Holy Spirit is God’s ‘guarantee’ or pledge, by which he undertakes to bring his people safely to their final inheritance. ‘Guarantee’ here is arrabōn, originally a Hebrew word which seems to have come into Greek usage through Phoenician traders. It is used in modern Greek for an engagement ring. But in ancient commercial transactions it signified a ‘first instalment, deposit, down payment, pledge, that pays a part of the purchase price in advance, and so secures a legal claim to the article in question, or makes a contract valid’ (AG). In this case the guarantee is not something separate from what it guarantees, but actually the first portion of it. An engagement ring promises marriage but is not itself a part of the marriage. A deposit on a house or in a hire-purchase agreement, however, is more than a guarantee of payment; it is itself the first instalment of the purchase price. So it is with the Holy Spirit. In giving him to us, God is not just promising us our final inheritance but actually giving us a foretaste of it, which, however, ‘is only a small fraction of the future endowment’.
