Holiness isn’t popular, yet only the holy will see God (He 12:14): He calls us to godly fear in perfecting it (2Co 7:1), continually cleansing ourselves of all uncleanness, all filthiness of the flesh and spirit. What does this mean? How do we do it?
Holiness is about our heart’s alignment with God’s Law, Torah, the law of love (Mt 22:37-40); it’s God’s measure of how disposed we are to seek His pleasure, of our inclination and tendency to love others as ourselves in deed and in truth.
So how would we live if we cared deeply for God and others? Perfecting holiness is striving every day to live out our answer to this question, exercising our inner selves, training our souls in godliness, purifying our spirits in seeking and obeying the truth through the Spirit unto authenticity and love (1Pe 1:22), seeking the pleasure of God and the good of others in every thought and choice. It’s continuous improvement for life. (Php 3:14)
Thankfully, the pursuit of holiness is itself the work of God, to make us increase and abound in love toward others, so that He may stablish us unblamable in holiness before Himself. (1Th 3:12) As we wrestle this out in daily life He strives in and through our striving (Col 1:29), ensuring our victory (1Co 15:57): He will be glorified in and through us. (2Th 1:10)
The context of 1Co 7:1 is coming out of the world and being separate.
Much of the world remains in us through our habits and carnal mindset. Any emotion or desire contrary to, or not fully consistent with God‘s heart must be addressed.
It is one thing to have our wills under control and to be making right choices, it is another thing altogether to have our hearts cleansed so our affections are consistently reflecting, holiness, and love.
If we do not cleanse these areas of latent darkness, the enemy will certainly leverage them in times of stress or duress, catching us by surprise and taking us captive.
