Everyone, from the time they are born, start to die because of sin. We live in a sin filled world. There are no exceptions, we are all in this boat. Those kids are dying at a young age because of the sins of generations before them. And there are kids dying at a young age in all countries for the same reason. And it is a terrible terrible tragedy. The bible talks about people who sacrificed their children in fires for the gods they believed in. They didn't believe in the real God but would do anything for the false gods, including sacrificing their own children.
The bible says the whole creation groans:
Romans 8:19-21
For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope 21thati the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.
I want to be free from this bondage of decay. I want those children to be free from the bondage of decay. God is the only one who can free us. He is making things new, and those who want to be a part of it all, can certainly be. God works in the minds of children just as He works in anyone. He can bring any of those dying children to Him. He has no limitations.
Revelation 21:1-5
Then I saw a new heaven and a new earth; for the first heaven and the first earth had passed away, and the sea was no more. And I saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying,
“See, the home of God is among mortals.
He will dwell with them as their God;
they will be his peoples,
and God himself will be with them;
he will wipe every tear from their eyes.
Death will be no more;
mourning and crying and pain will be no more,
for the first things have passed away.”
And the one who was seated on the throne said, “See, I am making all things new.”
