The spiritual gift of miracles is described in Scripture much like the gift of healing. It is found in 1 Corinthians 12:10 and the Greek phrase energemata dynameon literally translates “workings of powers.” The double plural most likely means that these gifts were diverse and were not permanently available at the will of the gifted believer, but instead were bestowed at various times and circumstances. Thus, the gifts are subject to the divine will of God and His purposes and are not decided by the one who performs the miraculous works.
We know that Jesus performed many miracles in His earthly ministry, even more than those recorded in Scripture (John 20:30-31, Acts 2:22). The Apostles regularly performed miracles of all kinds including casting out demons, healings, raising people from the dead, striking people dead, causing blindness, and much more (Acts 2:43; 3:1-10; 5:1-16; 9:36-43; 13:4-12; 19:11-12). Other believers performed miracles as well, including Stephen (Acts 6:8) and Phillip (Acts 8:4-8).
Miracles were given by God to the church to reveal the presence and glory of God among His people and to create a sense of awe and wonder and Godly fear. Though there were many enemies of the church, often the result of miracles being performed was more people coming to faith in Jesus and glorifying God, as well as greater faith and boldness within the church (Acts 4:29-31; 9:35, 42).
Those with the spiritual gift of miracles often have a heightened sensitivity to the presence and power of God through His Holy Spirit. They have a special measure of faith and desire for God to reveal Himself and draw many to faith in His Son Jesus Christ. They take care not to draw attention to themselves or have a following of people, but are constantly pointing others to Jesus. Those with this gift understand that God is Sovereign and He can work when and how He desires, but they make sure they are available and listening to the prompting of the Holy Spirit. This gift is often accompanied by prayer and strong petition by these individuals for God to reveal His glory to people. They do not claim power themselves, but always give credit and glory to God for His mighty works. Often God will deliberately humble them to keep them relying on His grace and pointing to His Son, rather than miracles. See also 1 Corinthians 12:10, 28-29; Acts 1:8; Galatians 3:5.
