I came to think about this question when I first became a Christian. I wanted so much for my parents to be saved, but to this day they’re still not. I thought at that time, if only I could trade something with God for their salvation, I mean anything, even my life. If God says, “Amy, in order for your parents to be saved, you have to die.” I would say, “Absolutely! Take my life!” Thankfully, Jesus has already given his life for my parents, and I am not qualified for the job anyway.
If one could give one's life up for another's salvation, I don't know how many Christians would give up their lives for Buddhist and Muslims. I thought of the decades of unceasing work in the gospel hard soil of Japan and numerous Islamic countries. The enormous amount of resources pouring in sure does not seem like it is ‘balancing’ the number of people saved. However, I am sure if you ask any one of those who are supporting ministries in these countries, who are working faithfully, who have given their lives for the people in these countries, “Is it worth it?” They will give you a definite "YES!"God, through this, is telling us that ‘balancing the salvation check book’ is not our concern, it's his business, all we need to do is to remain faithful to what he has called us to do, walk with him, look to him, feel his heart for the lost, the rest is God's concern, not ours.
