In this essay, Christopher Brown shares how the Lord led him into greater watchfulness, taking him from the snares of habitual sins into closer attentiveness to the roots of those sins and the work of the Holy Spirit purifying his heart. Following the witness of the saints of the Church, Christopher shows how the purification of our hearts leads us into the presence of God that we might receive His glory and love.
