Morning Star
This name (morning star or day star) is figuratively given to Christ (Rev. 22:16; compare 2 Peter 1:19).
When Christ promises that he will give the “morning star” to his faithful ones, he “promises that he will give himself to them, that he will impart to them his own glory and a share in his own royal dominion; for the star is evermore the symbol of royalty (Matthew 2:2), being linked with the scepter (Numbers 24:17). All the glory of the world shall end in being the glory of the Church.” Trench's Comm.
