God said, “I’ll meet the human race in only one place. That is the cross.” And if you haven’t been to the cross, there is no salvation and there is no forgiveness.
Worship in God’s Dwelling Place, Free to Choose Good. God gave the Scriptures to us as a guide so we know what is good and what is evil; nevertheless, it is up to each of us to either live according to God’s Word by accepting the good and rejecting the evil or to live according to the dictates of our own heart and the current cultural perspective or worldview.
Now C.S. Lewis does cover more eloquently how free will and an omniscient God could exist at the same time, could these great men and what I added be refuted? Yes of course, and it will be until the great white throne judgement day when all will be made clearer than a bell but until that moment there will be debate.
