“7 Do not ye err, God is not scorned; for those things that a man soweth, those things he shall reap [for why what things a man soweth, also these things he shall reap].
8 For he that soweth in his flesh, of the flesh he shall reap corruption; but he that soweth in the Spirit, of the Spirit he shall reap everlasting life.
9 And doing good fail we not [Forsooth we doing good, fail not]; for in his time we shall reap, not failing.”
Here Paul strongly reminds his readers in Galatia that circumcision of the flesh is not the proper means to everlasting life. They are sowing “in the flesh” rather than “in the Spirit.” They are seeking to obey the Law of Moses primarily to avoid the cross of Christ, i.e. crucifixion. They have forgotten they can not scorn God; they can not make their own way to heaven. They must take up Christ’s way and so “reap everlasting life” as they “soweth in the Spirit.”
“12For whoever will please in the flesh, these constrain you to be circumcised, only that they suffer not the persecution of Christ’s cross.
13 For neither they that be circumcised keep the law; but they will that ye be circumcised, that they have glory in your flesh [but they will you to be circumcised, that they glory in your flesh].
14 But far be it from me to have glory [Forsooth be it far to me to glory], but in the cross of our Lord Jesus Christ, by whom the world is crucified to me, and I to the world.
15 For in Jesus Christ neither circumcision is any thing worth, nor prepuce, but a new creature.”
Paul says, glory not in your flesh; glory only “in the cross of our Lord Jesus Christ.” Remember, what matters — what has worth — is being made “a new creature.” All the rest is corruption.
Have you heard — Christians can not sin? Have you heard — if you sin, then you are not really saved?
Paul says to the Corinthian church, “I do not write these things to make you ashamed, but to admonish you as my beloved children.” He claims to be their “father in Christ Jesus through the gospel.” As their father, he urges them to “be imitators of me.” (1 Corinthians 4: 14, 16) He commands the church to “cleanse out the old leaven that you may be a new lump, as you really are unleavened.” Paul writes to the Colossians, “If then you are raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. Set your minds on things that are above, not on things that are on earth. For you died, and your life is hidden with Christ in God. When Christ who is your life appears, then you also will appear with Him in glory.” (Colossians 3: 1 – 4) He calls them to “put to death therefore what is earthly in you.” (Colossians 3: 5)
Paul urges them not to be chained again “by philosophy and empty deceit.” (Colossians 2: 8) He tells them and us that we “are filled in [Christ], who is the head of all rule and authority. In Him, [we] are circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, having been buried with Him in baptism, in which [we] are also raised with Him through faith in the powerful working of God, who raised Him from the dead. And [we], who were dead in [our] trespasses and the uncircumcision of [our] flesh, God made alive together with Him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This He set aside, nailing it to the cross.” (Colossians 2: 10 – 14) God sets aside our record of debt. He eliminates legal demands. He puts off our body of flesh, and makes us a “new lump” in Christ. He makes us “unleavened;” this feat is accomplished “in the powerful working of God.”
Our part is to daily “put off” the old leaven, the old earthly self. This also is accomplished through the “powerful working” of God, the Holy Spirit. Hence, Paul admonishes his beloved children, not to shame them but to prod them towards the prize, the goal of their salvation.
