Taken from John Pipers sermon ‘My Heart’s Desire: That They Might Be Saved’:
We must feel compassion for the perishing and a longing for their conversion because our own salvation is such a precious undeserved gift. Surely it is unthinkable that we should be drug from the bottom of the lake, resuscitated at the cost of another’s life, handed the instruments of rescue, and then just sit down and play cards on the beach while others are drowning. Is that not unthinkable in your own life?”
Never forget that people who do not obey Christ forfeit eternal life and go out into eternity under the wrath of God. John 3:36, “He who believes in the Son has eternal life; he who does not obey the Son shall not see life, but the wrath of God rests upon him.”
Ask yourself questions like, “If I knew that a plague was coming and I knew that my colleague had not received the vaccination to protect himself, would I not inquire why she refused? Would I not seek to persuade her that she should choose life?” Ask yourself what you would say at the judgment day if your unbelieving friend turns to you and asks you why you didn’t speak to him with more seriousness about this matter of eternal life.
In other words, keep before your mind the terrible reality of entering eternity without Christ.
