Divorced from the holiness of God, sin is merely self-defeating behavior or a breach in etiquette.
Divorced from the holiness of God, grace is merely empty rhetoric, pious window dressing for the modern technique by which sinners work out their own salvation.
Divorced from the holiness of God, our Gospel becomes indistinguishable from any of a host of alternative self-help doctrines.
Divorced from the holiness of God, our public morality is reduced to little more than an accumulation of trade-offs between competing private interests.

The holiness of God is the very cornerstone of Christian faith, for it is the foundation of reality. Sin is defiance of God’s holiness, the Cross is the outworking and victory of God’s holiness, and faith is the recognition of God’s holiness. Knowing that God is holy is therefore the key to knowing life as it truly is, knowing Christ als he truly is, knowing why he came, and knowing how life will end.
