Last week I read this in John MacArthur’s book Truth for Today and it convicted me and helped me to increase my passion for lost people. He suggested the following five steps to increase your passion for lost people:
First, study Christ’s great love, compassion, and tender mercy. You can study great men and women in church history, but ultimately you must understand the heart of Jesus. As 1 John 2:6 says, “He who says he abides in Him ought himself also to walk just as He walked.”
Second, study sin: its guilt, power, and penalty. That will make you aware of how we have all fallen prey to the subtleties of the world. Romans 12:2 says, “Do not be conformed to this world, but be transformed by the renewing of your mind.” Let it remind you to be preoccupied not with worldly things, but with evangelizing the lost.
Third, study sinners. Try to cultivate love and sympathy for them, not bitterness. Note that the most zealous evangelists are often new converts.
Fourth, study Scripture. See what it says about hell, death, judgment, and salvation.
And finally, pray for God to give you a passion for evangelism.
