There are different ways God works in our lives, but it is the same God who does the work through all of us.
A spiritual gift is given to each of us as a means of helping the entire church.
To one person the Spirit gives the ability to give wise advice; to another he gives the gift of special knowledge.
The Spirit gives special faith to another, and to someone else he gives the power to heal the sick.
He gives one person the power to perform miracles, and to another the ability to prophesy. He gives someone else the ability to know whether it is really the Spirit of God or another spirit that is speaking. Still another person is given the ability to speak in unknown languages, and another is given the ability to interpret what is being said.
References for 1 Corinthians 12:10
It is the one and only Holy Spirit who distributes these gifts. He alone decides which gift each person should have.
The human body has many parts, but the many parts make up only one body. So it is with the body of Christ.
Some of us are Jews, some are Gentiles, some are slaves, and some are free. But we have all been baptized into Christ's body by one Spirit, and we have all received the same Spirit.
References for 1 Corinthians 12:13
Yes, the body has many different parts, not just one part.
If the foot says, "I am not a part of the body because I am not a hand," that does not make it any less a part of the body.
And if the ear says, "I am not part of the body because I am only an ear and not an eye," would that make it any less a part of the body?
