As a Christian and a scientist/engineer (though not a Christian Scientist) I find that it *is* possible to believe in God and Christ as savior and Lord, and still deal with the world in a rational and scientific manner. We were created by God in his image, as a painting or scupture might be the image of it's artist.
Evolution is the process of that creation:
As an artist might chip away bits of marble to make a statue, God refines and polishes his creations, improving and perfecting us
