This episode applies the "half-and-half" strategy of Nehemiah to the body of Christ, in which, on the one hand, we're called to actively work in ministry, but on the other, we protect the progress we've made up to that point. All of Nehemiah's men participated in building the wall, but carried swords while they were building. Every Christian should work in ministry in some capacity, while adopting a defensive posture to protect what the Holy Spirit has done. Interestingly, the primary adversary of the Christian is not the "evil" out there, but his own residual sympathies towards evil, in which casting down thoughts, imaginations and strongholds is the responsibility of every Christian when dealing with himself. This defensive posture is absolutely necessary when actively working to build up the body of Christ.
A “milk will do” attitude might indicate a fake conversion
Based on the Scriptural description that the ultimate purpose of salvation is service to God and not merely the forgiveness of sins, this episode unpacks the "milk will do" attitude towards spiritual growth and shows how this nonchalant attitude towards growth in Christ might be a sign of false conversion. True Christians are not ultimately content with their "sins being forgiven for Christ's sake." Based on the born again experience, they have a principle within them that they long to please and serve God, irrespective of the ultimate consequences of sin in heaven or hell. So true repentance from dead works is not content will a "milk will do" attitude, resting in the forgiveness of sins. It presses on to maturity to serve God.
The Role of the Word in Repentance
This episode rehashes all the influences of the Holy Spirit indicative of the circumcision of Christ. Unregenerate man is dominated by the flesh and incapable of distinguishing flesh from spirit. This state changes when he is born again and circumcised by Christ, making the believer better at distinguishing flesh from spirit. But this ability is compounded exponentially when the Word of God is consumed by the Christian. With respect to repentance from dead works, the Word of God exposes us to ourselves so that we can discern what is fleshly and respond in repentance.
