LK18:38-And he cried, saying, Jesus,thou Son of David, have mercy on me.
In Yoruba land, when you beg a man to do something for you or you need his favor, when you begin to chant his lineage praise, you will touch the soft spot in him/her, by so doing, you will get your request quickly.
Some even went to parties with little cash but as soon as someone began to chant their lineage praise, some will rush home to get more money because their soft spot was touched.
That man cried to Jesus&located His roots. He didn't say Jesus have Mercy on me but he said, JESUS, thou, Son of David, Have mercy on me. It is only a bastard that will hear men call him from his lineage root without moving an inch.
If you need Mercy, call Him from the root, there are many types of Jesus today, but we have only from the root of Jesse, the son of David.
Call Him from the root.
Jesus Christ, Son of David, Have mercy on me In Jesus Name.
