You painted a poignant poetic picture of the passion of the Christ.
When you talk about Red, it reminds me of the Blood of the passion for a bride; Christ shedding His Blood to pay the dowry of His Bride, the Church.
When you talk about Thorns of black, it paints the picture of the Crown of thorns the Lord Jesus wore as He took the ridicule of those who didn't understand His kingship.
Brilliant poem. God bless!
