According to Wikipedia: A miracle is an event not explicable by natural or scientific laws. While strongs definition: the word for miracles “dynamis” is described as (miraculous) power, might, strength, physical power, force, might, ability, efficacy, energy, meaning “ability to perform”, power to achieve by applying the Lord’s inherent abilities.
Miracle workers are the ones who operate in the gifting of the miraculous, such as: walking on water, stilling the storm, creative healings such as the growth of limbs, or the supernatural multiplication of resources. Occasionally we see miracles happening today as gemstones on carpets, having extra strength to lift a car from a person trapped underneath.
The office of a miracle worker is to connect with people who operate in this gifting by teaching and encouraging them to step out of the boat and walk on water. This does not mean to focus on flattery but to bring correction and guidance wherever is needed, so they all can attain and be in total agreement in the faith and of the knowledge of the Son of God. Understanding that we, you-manity, are in the Godhead, one with The Father and the son.
