How do we know that the dead in Christ are blessed?

The confidence in the blessedness of those who die in Christ stems from divine revelation as articulated in the Bible, particularly in Revelation 14:13. This pronouncement comes directly from God or His appointed messenger, thereby affirming its truthfulness. The dead who are said to die in the Lord embody traits of faith, love, and obedience, indicating their commitment to Christ throughout their lives. This suggests that their faithfulness and the grace of God grant them a blessed state beyond death, a belief reinforced by the witness of the Holy Spirit, which confirms their eternal happiness and rest.
