Paul’s words to the Corinthians (2Cor.5) sum up the essence of obedience in the New Covenant (3.6):
In 5.14, Paul speaks of our actions springing from the love of Christ for us, in His having died (5.15) for us. This alone is the exclusive cause of our not living for ourselves but for His sake.
For, in Christ, we are no longer regarded according to the flesh (5.16), but are now partakers of the new creation (5.17) through the ongoing transforming ministry of the Spirit (3.6,8,18); all of which is of God (5.18)!
We then are partakers of a most glorious and permanent ministry of righteousness (5.21; 3.9,11), and are equipped with the weapons of righteousness (6.6,7), not waging a fleshly warfare (10.3-5), according to a ministry of death and condemnation that no longer has any glory (3.7,9,10)!
So then, it is Jesus Christ we proclaim (1.19; 2.17), in whom all the promises of God are fulfilled (1.20) and by whom we are enabled freedom by the Spirit (3.17) from every defilement of the body (physical sins) and spirit (idolatry) (7.1) unto a maturing holiness unto the Lord.
Our having fellowship with the Holy Spirit (13.14) – who writes His letter upon our heart (3.3) – is antithetical to a ministry of Stone (3.6).
Being mindful of these things, we maintain a sincere and pure devotion to Christ and resist the Devil’s first lie (11.3) that mere knowledge of “right and wrong” suffices, which is nothing more than “another Jesus,” a “different spirit,” and a “different gospel” (11.4).
