Angels are just as active today as they were in Bible times. Angels are spiritual beings that seldom assume physical form, which is why we don’t see them and are largely unaware of their presence. But I am convinced that when we get to Heaven, we will be amazed to discover how often God’s angels intervened to help or protect us. The Bible says that God “will command his angels concerning you to guard you in all your ways” (Psalm 91:11).
Are not all angels ministering spirits sent to serve those who will inherit salvation?
