The Holy Spirit teaches us that he can do the impossible. He allowed Mary, the mother of Jesus to get pregnant with Jesus. This is before she had any sexual relations with a man. If he can do that for Mary, imagine what he can do for us.
According to the Bible, we cannot stop mankind from doing evil to us. We also cannot stop it from coming our way. However, God’s angels help us to see that they can warn us about things that are going to happen. It is amazing how we think that God has to keep all evil away from us. For some reason, he allows this evil to come to us and he gives us the tools to help us along the way by giving us angels and people that come into our lives for help and to lead us away from danger.
