"Why Ruby Kingdom?
In the Bible, rubies symbolize sacrifice, atonement, and the blood of Christ. As the first stone in the High Priest's breastplate (Exodus 28:17), they represent the tribe of Judah and the blood-red, redeeming sacrifice necessary for atonement. The deep red color of the ruby is tied to the blood of Christ, representing divine sacrifice and the shedding of blood for the forgiveness of sins. Rubies are used throughout the Old Testament (Job, Proverbs) to represent the highest level of preciousness, often to highlight that wisdom, virtue, and a godly woman are far more valuable than the stone itself. The ruby is also linked to the blood-red atonement (Isaiah 54:12), which signifies security in Christ's sacrifice, along with being a foundation stone of the New Jerusalem
(Revelation 21:20).
Kingdom is defined as the spiritual reign or authority of God. It comes from the Greek word Basileia (βασιλεία) and appears 342 times in the King James Version of the Bible, 162 of which occur in the New Testament. God sits on his throne as king, "in all the heavens, and his kingdom rules over all" (Psalms 103:19). He governs all things and keeps his covenants to all people by not abandoning us and offering salvation through grace.
