6:16 What profound teaching is underlined by what Paul says here?

The whole of what the Bible teaches is encapsulated in this verse; that obedience to God means everlasting life, and disobedience means death. This is the gospel of salvation in one verse (CP Jn 3:17-20, 36; Ro 2:7-11).

The eternal destiny of every living soul is determined by whom they choose to obey. Paul affirms in Ro 6:16 that even though Christians are under grace it is still their responsibility to resist sin and obey God (CP V11-13; 8:12-14; Eph 5:3-10; Col 3:1-13). We can yield to sin and go to hell, or we can obey God unto everlasting life with Jesus. We cannot serve sin and Satan and expect to rule and reign with Christ in eternity.

No man can be a servant of sin and Satan, and a servant of righteousness and Christ at the same time (CP Pr 5:22-23; Mt 6:22-24; Jn 8:31-35; Ga 1:10; Jas 4:4; 1Jn 2:15).

Jesus makes it quite clear in scripture that if Christians are not totally consecrated to the service of God and completely yielded to the authority of Jesus they are none of His (CP Mt 12:43-45; Lu 11:23-26).

This clearly teaches that the Christian walk is not a neutral zone. We are fighting either on the side of Christ and righteousness, or we are on the side of the devil and the ungodly. Lu 11:24-26 teaches that unless after our conversion to Christ we quickly fill the void in our lives left by sin with the righteousness of God, our old sinful nature will reassert itself and we will be actually worse off than we were before we got saved (CP Jn 5:14; He 6:4-6; 10:26-31; 2Pe 2:20-22).

The only safety from sin and Satan is to be totally consecrated to the service of God and completely yielded to the authority of Jesus. Anything less will cost us our place in the kingdom (CP Mt 7:21-27; Ro 2:13; Jas 1:22-25).

Believers who are not actively involved in opposition to Satan and the evil of this world, have in reality set themselves against Jesus. That is what Jesus means in Lu 11:23 when He declares that "He that is not with me is against me; and he that gathereth not with me scattereth." Jesus here is clearly condemning any attempt at compromise with unrighteousness, or only partial obedience to Him. It is all or nothing as far as Christ is concerned (CP De 6:13-15; Josh 24:19-20; Nah 1:2).
