What is the earnest of our inheritance in Ephesians 1:14?

The earnest of our inheritance is the sealing of the Holy Spirit—the down payment guaranteeing what is to come. It remains until the redemption of the purchased possession, which includes the future redemption of the body, not just the already-redeemed soul and spirit.

Les explains from Ephesians 1:14 that the sealing of the Holy Spirit is the earnest, the down payment, of our inheritance until the redemption of the purchased possession. He notes that God has already redeemed the soul and spirit, but what is still waiting is the redemption of the body. Les then points to Romans chapter 8, where Paul says everything is moving toward the day when we will have that final redemption of the body. At that point we will be a complete entity, ready to go into all eternity. This ties the Holy Spirit’s sealing to the coming new body and complete redemption.
