I have no greater regret than hurting people in the past. People who were growing spiritually, but fell away after I put my emotions over their eternity, leading to a remembrance of despair instead of integrity. The Kingdom of God is likened to a great pearl, so great that a merchant sold everything to have it. In retrospect I wonder, "What would I have not given to see them in heaven?"
"Greater love has no one than this, that he lay down his life for his friends." (John 15:13) If you could ensure someone's eternity, what would you be willing to give to do that? What would I be willing to give up to give someone a good chance? What would I be willing to sacrifice? How far would I be willing to love someone?
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
