Grandchildren are a blessing, there is no denying that. And, entering the priesthood does mean that your son will not have any biological children. This is, undeniably, your sacrifice in supporting your son as a priest. Reflect, though, upon the powerful impact a dedicated priest has on the many people he meets, and upon the value of accepting God’s will in life, even when it may be difficult. A priest’s life is a life of sacrifice, because it is the life of our Lord. The parent of a priest will also make sacrifices in this life for the greater glory of the next, because their life is that of the Blessed Virgin Mary. Ask Mary to pray for you for wisdom and understanding, as your son discerns God’s will in his life.
