What does the Bible say about who will dwell in heaven?

Psalm 15 poses the profound question of who shall dwell in the Lord's holy presence. The answer is given in verse 2, which outlines the character of those bound for heaven: they walk uprightly, act righteously, and cherish truth in their hearts. This righteousness is defined not by human standards but by divine perfection, as the Lord Jesus spoke of those who recognize their need for Him as blessed. This underscores the eternal truth that only those reflecting the character of Christ and reliant on His righteousness can enter into glory.
