In spiritual life, in interpersonal relations, in all of our work, this principle holds true: the path to gain is through pain. (13)

This is an unbiblical generalization and emphasis. Beeke probably wishes to universalize and legitimize his own experience, negativity, and unbelief. The kingdom of God is righteousness, peace, and joy in the Holy Spirit. Gain in the spirit comes from faith, hope, love, knowledge, cooperation, grace, mercy, holiness, victory, and many other wonderful things. Instead, Beeke stresses pain. This is what he thinks of the Christian faith, and of Jesus Christ. He also applies this to interpersonal relations. So this is what he thinks about his wife, his children, and his friends.

Faithless religion is mindless and infuriating, yet confidently pretentious. Entirely delusional. It is a spiritual and mental illness.
