So we no longer pursue plainness and simplicity of life. We no longer value stillness, which helps to free us from past defilement, but prefer a whole host of things which distract us uselessly from our true goal. Rivalry over material possessions has made us forget the counsel of the Lord, who urged us to take no thought for earthly things, but to seek only the kingdom of heaven (cf. Matt. 6:33). Deliberately doing the opposite, we have disregarded the Lord’s commandment, trusting in ourselves and not in His protection.
