Exodus 33:12- 23; Rev 21:1-7 and Mk 6:45-51.
The typical miracle in Mark is to do with healing, often combined with casting out unclean spirits, making the blind see, the deaf hear, and so on. Very good things to do. Nowadays we understand far more about illness and medicine---so these miracles aren’t quite as supernatural for our consciousness. In the gospel, faith (your own or someone else’s) is a condition to be healed, or there is some other theological overlay. Nevertheless it’s all in line with a universal human want and something we’ve got quite good at ourselves.
