He is lovely to God His Father, lovely to the saints, and lovely to the angels.
1. He is lovely to God His Father. God is infinitely delighted with Him. Christ is called "the Rose of Sharon," and how God delights to smell this rose! Isaiah 42:1: "My Chosen One in whom My soul delights." Surely if there is loveliness enough in Christ to delight the heart of God, there may well be enough in Him to delight us. Christ is the center, where all the lines of His Father's love do meet.
2. Christ is lovely in the account and esteem of His saints. 2 Thessalonians 1:10: "He shall admired by all those who have believed." He is admired now — and He shall be more admired by them. Well may the saints admire to see Christ sitting in the bright robe of their flesh above the angels in glory. Well may they admire to see their nature united with the Deity. Oh, how lovely and beautiful is this sight! Well may Christ be admired by His saints.
3. Christ is lovely in the esteem of the angels. They adore Him. Hebrews 1:6: "And let all the angels of God worship Him." The cherubim are painted with their faces looking upwards, to show that the angels in heaven all are still looking upward, admiring and being ravished with the amazing beauties of Jesus Christ.
Do it Father, please ravish us with all His beauties! For Jesus' sake!
Thomas Watson, The Loveliness Of Christ
