Paul after having explained the depravity of carnal man now explains the glorious truth about the Holy Spirit. It is the coming of the Holy Spirit that changes everything about our old sinful life. Holy Spirit enables us to call God as Father. Without the Spirit, there would be no holiness possible. The Spirit of God also gives us true assurance of our salvation. But despite being a child of God, sufferings in life are inevitable. Groanings, sufferings are an integral part of Christian life which will eventually lead to Glorification of the Saints. A child of God groans because of tribulations, because of the decadent nature and also because he/she longs for the presence of God. Ultimately God is the heritage and exceedingly great reward of His Children.
