Psalm 15:1-2 (KJV)
15 Lord, who shall abide in thy tabernacle? who shall dwell in thy holy hill?
2 He that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart.

Who shall dwell in thy holy hill? - Zion, regarded as the dwelling-place of God, and the type of heaven - the eternal abode of the Most High. See the note at Psalm 2:6. The question is equivalent to asking, who is qualified to dwell with God? who may properly be regarded as his friend? who has a title to his favor? who is truly pious? By us the same question would be put in another form, though implying the same thing: Who is qualified to become a member of the church; who has evidence of true conversion and real piety? who is he who is prepared for heaven?
