The main point thus far: Even while we claim the meritorious mortification of our sin through the work of the cross of Christ, and though the implantation of our new life in Christ is in opposition to and destructive of the expression of sin, sin remains, acts, and works in the best of believers while we are yet in this world. It must be our constant daily duty to mortify it.
Before proceeding, I cannot but note that even though there is in this generation a growing number of professors, a great noise of religion, religious duties in every corner, and preaching in abundance, there is little evidence of the fruit of true mortification. Perhaps we might find that ,judging by the principle of mortification, the number of true believers is not as multiplied as it appears from those who have made a mere profession. Some speak and profess a spirituality that far exceeds the former days, but their lives given evidence of a miserable unmortified heart. If vain spending of time, idleness, envy, strife, variance, emulations, wrath, pride, worldliness, selfishness (1 Cor 1), are the mark of Christians, we have them among us in abundance. May the good Lord send us a spirit of mortification to cure our distempers, or we will be in a sad condition!
There are two evils which certainly accompany every unmortified professor, the first, in himself, and the second, with respect to others.
First, in himself. The basic characteristic of an unmortified course is the digestion of sin without bitterness in the heart. He who is able to swallow and digest daily sins in his life without conviction in the heart is at the very brink of turning the grace of God into lasciviousness, and being hardened by the deceitfulness of sin.
Let a man pretend what he will, little concern over sin is a serious offence to the grace and mercy of God!
There is no greater evidence of a false and rotten heart in the world than to deal in such a trade. To claim the blood of Christ, which is given to cleanse us (1 John 1:7; Titus 2:14); the exaltation of Christ, which is to give us repentance (Acts 5:31); the doctrine of grace, which teaches us to deny all ungodliness (Titus 2:11-12); and then to allow sin, is a rebellion that in the outcome will break the bones. From this door have gone out from us most of the professors that have apostatized in the days in which we live. For a while most of them were under conviction, and they ‘escaped the defilements of the world through the knowledge of our Lord and Saviour Jesus Christ’ (2 Pet 2:20). But after having become acquainted with the doctrines of the gospel, they became weary of their spiritual duties. They had no true desire for these, and they allowed evil instead to lay hold of them, and speedily tumble them into perdition.
Second, to others. Unmortified professors have an evil influence on others in two ways:
i. Others are hardened in their own sin by persuading themselves that they are in just as good a condition as the unmortified professor. They see their zeal for religion, but it is not accompanied with righteousness. They view their worldly and selfish lives. They see them talk spiritually but live vainly. They hear them mention communion with God, and yet they are in every way conformed to the world. They see them boast of forgiveness of sins, and yet never forgive others. Thus, as they see the stain of sin in the unmortified professor, they harden their own hearts in their unregeneracy.
ii. It deceives them to think that if they can just be as good as the unmortified professor it shall be well with them. In reality they might even go farther in ‘holiness’ than the unmortified professor, and yet still fall short of eternal life.
