Today I saw a small white feather which I know many people see as a good sign from God that His angels are at work. I don't think there is a bible verse which specifically tells us that, let alone tell us that angels have white wings. In whatever way we may tangibly see God at work in our lives, even if fanciful, the truth is that God is indeed wanting to guide and protect us constantly. Whether we receive this truth or not is our choice. In Psalm 63:7, King David declares, "Because You have been my help, therefore in the shadow of Your wings I will rejoice".
