As you grow in dependence on the Lord, and learn how He moves through the operation of the gifts, you will become more and more comfortable to be available to be used by Him in whatever capacity He chooses. Say the Lord has been flowing through you in the gift of healing, but gives you the discernment that what is needed for the person is a word of wisdom, understanding, to enlighten his situation. Ask the Lord, "What do you have for this person?" The Lord may choose to give Himself through you, or through another person. The point is that, from your point of view, this may be an opportunity to begin letting the Lord minister through you in the gift of a word of wisdom. There is a danger in becoming "specialized" and in letting others decide how you should minister, to whom, and when. God doesn't appreciate it when others usurp His authority, and His "order" is not like ours.
