It is not "Evolution" that Christians struggle with, but rather Darwinism
It is important that people understand the major differences between Macro-evolution and
Micro-evolution.
While not ALL Christians will agree with me here, I think the majority (on one level or another) will agree that God allows for adaptations, in His own creation. This kind of "micro-evolution," both Atheistic Darwinist and Christian scientists both will typically agree does occur in real life.
The Darwinists take these adaptions and make them into something much bigger than they really are. They claim that the adaptions are actually mutations and they are good mutations because through the course of natural selection...these are the mutations are essential for survuval. Survival of the fittest.
Where Christians will differ largly is that these adaptions are natural and a part of God's plan. He made each and every animal unqice and special. Some would survive and others not.
The biggest difference between Christians and Darwins is the begining of all Creation. Christians believe that the world was created by God.
But even Darwinism did not claim an absolute "origin of all life." Despite the obvious play on words - the tilte of Charlse Darwin's book.
The biggest mistake Christians claim from within Darwinism is the origin of ALL beings from a one cell being. This type of macro-evolution, you will not find in Christian belief. God created each being unique and seperate from each other.
While Darwins try to find and exagerate the similarities between all beings. Christians find beauty in the differences. We stand in awe and wonder in how each and every being/species were created by God.
While Darwins stand in wonder of how each and every species developed from a one-cell being.
Christians stand in wonder of how each and every species developed from one being, Almighty God.
