The lover of our souls said in Hosea 2:19 "I will betroth you to me forever. I will betroth you to me in righteousness and in justice, in steadfast love and in mercy. I will betroth you to me in faithfulness. And you shall know the Lord." In the 16th verse He says, "you will call me my husband and will call me no more my master."
When he asked the disciples around the table to take of the bread and the wine, he was sealing a covenant with them.
In Judaism, the bridegroom asks for the hand of the bride by pouring a cup of wine for his bride to be and then he waits for her to respond by drinking from the cup. She is saying "yes" and this symbolizes the sealing of their marriage covenant. They were now engaged. They belonged to one another for the rest of their lives. They had sealed a covenant. Then a price was offered for the bride.
Jesus was about to go to the cross to pay the price of the bride. His death and the shedding of His holy blood.
He has sealed our marriage covenant with His blood. We are His. He purchased us. "Drink ye all of it."
Treasure this remembrance each time you do it. We are awaiting His return. He has not drank of the fruit of the vine since that day in the upper room. But one day, He will. With us. Together. Around His table. As we are forever wed to our Beloved.
Say "yes" to Him. Again, and again, and again! You are sealed. Enjoy it!
