What truly distinguishes Christianity from Islam?

I went back n watched the whole stream since I was in n out earlier. I missed a couple of things and learned something. 1/scratch what I said earlier, you were right. If in Islam a predetermined destiny already decides every action, big or small, doing deeds to earn favor doesn't make sense. 2/ I agree with u about submission. Christianity has submission cause God gave us free will, so we have the choice to hand it over to Him. Islam doesn't have submission cause without free will, there is nothing to give away..destiny is already controlling everything

In Christianity, we have a good, good Father, our God JESUS CHRIST who luv us, died on the cross, and paid for our sins. On the other hand, Islam focuses on earning God’s favor through deeds
