“You’re blessed when you get your inside world—your mind and heart—put right. Then you can see God in the outside world.
Matthew 5:8 MSG
The pure in heart — Those whose hearts are purified by faith; who are not only sprinkled from an evil conscience by the blood of Jesus, but cleansed by the Spirit of God from vain thoughts, unprofitable reasonings, earthly and sensual desires, and corrupt passions; who are purified from pride, self-will, discontent, impatience, anger, malice, envy, covetousness, ambition; whose hearts are circumcised to love the Lord their God with all their hearts, and their neighbours as themselves, and who, therefore, are not only upright before him, but possess and maintain purity of intention and of affection in all their designs, works, and enjoyments; serving him continually with a single eye and an undivided heart. They shall see God — Namely, in the glass of his works, whether of creation, providence, or grace, here, and face to face hereafter: they shall have fellowship with him in his ordinances, and shall endure as seeing him that is invisible, while they walk by faith on earth, and shall be admitted to the most perfect vision and complete enjoyment of him in heaven.
