There are natural miracles such as, the complex and intricate workings of the systems in our body; sleep and waking up, how the body heals itself when a bone breaks; rainfall  and vegetation; etc. And there are supernatural miracles – direct, out-of-the-norm action and interventions of God. Miracles are usually instant but they can also be progressive. Examples are as mentioned in the Bible “that very hour”: blind eyes opening, the deaf hearing, dumb  speaking, lame walking. For progressive: conception and birth; recovery from damage caused by severe accidents; change in financial situations, family dynamics, etc.
