This exaltation of the cross has a direct link to the Gospel reading from the Holy Qurbana of Mid Lent. John 3: 14-15 says "And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life." Moses lifted up the bronze serpent around the middle of the Exodus, the journey of the Israelites from slavery to their promised land. He lifted up the serpent so that those who are bitten by the snake might look at it and have life. Similarly we at the middle of our lenten journey, also lift up the cross so that those who are bitten by sin can look at it and gain eternal life by the cross.
