Psalm 15, NKJV
Lord, who may abide in Your tabernacle? Who may dwell in Your holy hill?
2 He who walks uprightly, and works righteousness, and speaks the truth in his heart; 3 he who does not backbite with his tongue, nor does evil to his neighbor, nor does he take up a reproach against his friend; 4 in whose eyes a vile person is despised, but he honors those who fear the Lord; he who swears to his own hurt and does not change; 5 he who does not put out his money at usury, nor does he take a bribe against the innocent. He who does these things shall never be moved.
I only know of One who fit this description perfectly – Jesus, our Substitute, our Savior and Lord, our Example. Through Him alone can we dwell on God’s holy hill.
