Verses 30, 31

It is precious for us to know that the Christian has been sealed for the day of redemption, for the day when his body will be raised. When Christ shall have accomplished all that for which He died, our body (for Christ has redeemed it) will be raised, which has not yet taken place. It is said that Christ has been made to us wisdom, righteousness, sanctification, and redemption; redemption is put the last. It is not here the price paid for the purchase that is spoken of, but the result of this purchase. There are two things to be remarked in what follows: the new man and the Holy Spirit. The Holy Spirit is not created, He is an independent Being in us; we must not grieve Him: all that which accords not with the Holy Spirit is not suitable for the Christian. On the other hand, we see that we have full assurance; God has set His seal upon us; and this strengthens faith. We enter into the thoughts of God; we do not only find there the motives of holiness, but also the power of holiness. That which assures me of redemption puts me on my guard not to grieve the Holy Spirit. If we are in the presence of our Father, His love prevents us from falling. It is thus that the Holy Spirit seals us for the day of redemption, and guards us from evil.
