Spiritual gifts are for edifying the body of Christ.
Matthew 10:8 Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.
Elisha refused the gift from Naaman because he realized that Naaman was trying to pay for his healing. If people make you, they will distroy you. Prophesy as God speak and direct you not as people want you to.
2 Kings 5:15-16 Then Naaman and his entire party went back to find the man of God. They stood before him, and Naaman said, “Now I know that there is no God in all the world except in Israel. So please accept a gift from your servant.” But Elisha replied, “As surely as the LORD lives, whom I serve, I will not accept any gifts.” And though Naaman urged him to take the gift, Elisha refused.
