Some christians think they can just shelve to question of evolution because they think," preaching the gospel is more important." They fail to realise that the creation account is a vital part of the gospel. It tells us of a holy, righteous and good God who made all things. It tells us of Adam and Eve created perfect but who rebelled against God, passing sin onto the rest of us. It tells of God's promise to send a Saviour from Eve's seed who would crush the serpents head and redeem His people. Without the creation account telling us of our indebtedness to God as our creator and our need for the salvation He promises, we cannot understand the gospel as it later unfolds. We cannot ditch the creation account in favour of evolution. Without the creation account nothing else makes sense in the gospel. Your choice is simple, either be a Bible believing Christian (for there is no other sort) or ditch it in favour of evolution and be an atheist.
