Christ does not marry a building.
Peter tells us we are living stones: "As you come to Him, the living stone, rejected by men but chosen and precious in God’s sight, you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture: “See, I lay in Zion a stone, a chosen and precious cornerstone; and the one who believes in Him will never be put to shame.” (Peter2:4,5,6) When Solomon built his temple there was no sound of a hammer or chisel. Because the stores were formed in the quarry. "In building the temple, only blocks dressed at the quarry were used, and no hammer, chisel or any other iron tool was heard at the temple site while it was being built." (1Kings 6:7)
So the letter b represents a dwelling. Today there are lots of dwelling places all over the world. The idea is that God wants to dwell with man. "God's dwelling place is now among the people, and he will dwell with them." (Rev21:3) This is the very first letter in the Bible. This shows us God's desire to become a part of His Creation and to dwell with us. The Be stands for "Ben" this means the Son of God. The Son of God was given as a grain offering to reconcile heaven and earth so they could become united as one. This is why Jesus teaches us to pray: "Thy Kingdom come, Thy Will be done, on Earth as it is in Heaven". (Lords prayer)
