Is our salvation complete or only partial?
Salvation is complete for the soul and spirit—redeemed, justified, sanctified, and in the body—but only partial concerning the body. The Holy Spirit is God's earnest or down payment of the purchased possession, indicating the body is the third part that must be ready for eternity.
Les explains that after a person hears the word of truth, the gospel—that Christ died and rose from the dead—and believes, God seals them with the Holy Spirit of promise. That sealing is the earnest, the down payment. Les says we thought salvation was complete, and it is yes and no: complete for the soul and spirit—redeemed, justified, sanctified, in the body—but one part of the great plan of redemption is only partial. The purchased possession includes a third part, the body, which has to be ready for eternity. At salvation, the Holy Spirit comes in as God's earnest or down payment of the purchased possession, which will all redound to the praise of His glory.
