Romans 8:23, Redemption of the Body
Believers are the “firstfruits of the Spirit” in that the Holy Spirit indwells all who adopted into the family of God giving them the power to overcome sin. The believer can choose to yield to temptation and thus sin against God. The groaning that the Apostle Paul speaks of is the weariness that comes with that constant struggle. Satan and the world will continue to seduce the believer to their fallen ways. Each time the believer falls, he pays a price for the consequence of sin.
