Think also about what your salvation cost the Son. This is what salvation cost the Son. Think also about what salvation continues to cost the Holy Spirit. Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ. The phrase I want to center on here is sanctification of the Spirit.
Sanctification means purification or holiness.
So the high cost which the Spirit of God continues to pay for you is the tireless work of leading you to take the right path, the work of purifying you. Think back on your life and think about how hard this job must be. The Spirit is truly long-suffering if He can put up with the sins which we all at times commit. I hope that made someone perk up. If you are crucified with Christ then you are no longer living for yourself you are now living for Him.
