In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that 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, unto the praise of his glory.
(Eph 1:13-14)
What does it mean that the Holy Spirit is the earnest of our inheritance?
Keep in mind that an earnest is like a down payment.
Say, for example, a person decides to buy a house and puts down earnest money on it and then later backs out of the deal. What happens to the earnest money? The person it is paid to keeps it.
What does this say about our salvation?
