This sermon unpacks Jesus' beatitude, "Blessed are the pure in heart, for they shall see God," and shows that this is not an impossible command for Christians but a real description of those who have received a new heart in Christ. Drawing from passages like Jeremiah 17, Ezekiel 36, Psalm 24, Hebrews 11, and Exodus 33, it contrasts the deceitful heart of the unregenerate with the Spirit-transformed heart that can pursue purity, blamelessness, and obedience. The preacher presses believers to live consciously in God's presence, to train their hearts by thinking on what is true and lovely, to beware of sliding into sin, and to see God's glory both now—in creation, common grace, and human gifting—and fully in the age to come.
