"The Fulfillment of All Desire" is the title of a great book on the spiritual life authored by Ralph Martin. Have you ever wondered about heaven and, particularly, about whether or not we will know each other there? For example, your spouse, your best friend, your parents or siblings, your mother-in-law...St. Catherine of Siena was a mystic in the 1300's and is a doctor of the Church. She actually touches on this theme in her work "The Dialogue," which is a conversation between her and God the Father.
In 1 Samuel 18 the future king David has a beautiful and profound friendship with Jonathan, the son of Saul. It says that Jonathan loved David as he loved himself. This endures even when his father out of jealousy ends up seeking David's life. It is a beautiful example of friendship in the Bible. St. Catherine says in her work, and this is cited by Ralph Martin in his, that not only will we know and recognize each other in Heaven, but our friendship will be even deeper and more intimate. Those healthy friendships we have in the Lord will only reach new heights.
So look forward to heaven! And let's strive to live friendships now in anticipation of how they will be there.
