Songs of Solomon 2:1 says:: I am the rose of Sharon, and the lily of the valleys. Here Jesus, the groom, compares Himself to the Rose of Sharon. Sharon was a region known for it's beauty.
In Isaiah 35:1 says: The wilderness and the solitary place shall be glad for them; and the desert shall rejoice, and blossom as the rose.
I believe that wathever is impossible in our human eyes, is possible for God, that even the desserts shall blossom like the rose!
The Rose is also a symbol that you may blossom in your spiritual life in Christ!
