[Matthew 5:8] Blessed are the pure in heart, For they shall see God

[Psalm 15:1-2] LORD, who may abide in Your tabernacle? Who may dwell in Your holy hill? He who walks uprightly, And works righteousness, And speaks the truth in his heart;

[Psalm 24:3-5] Who may ascend into the hill of the LORD? Or who may stand in His holy place? He who has clean hands and a pure heart, Who has not lifted up his soul to an idol, Nor sworn deceitfully. He shall receive blessing from the LORD, And righteousness from the God of his salvation.

[Hebrew 12:14] Pursue peace with all people, and holiness, without which no one will see the Lord:
