Question:
First, as to gifts:
I believe there are “gifts” given (or acquired) by people which are based on real sensitivities or talents. I believe they exist as part of the talents brought into this life. Some people have talent to sing, compose music, or create art. There are those who have developed spiritual gifts. There are many kinds of gifts, but they all come from God. (Moroni 10: 8.)
Possession of a gift, however, does not mean a person will use that gift in conformity with God’s will or plan. If a person does not seek to follow the Lord’s will, they can be misled and use gifts for improper ends. People who fail to remain obedient, who begin to use their gifts to gratify their pride or to achieve their ambitions can drift away from the light and take others with them. Just because a person possesses a gift does not mean they live their lives in conformity to truth. Nor does it mean they will not mislead you. Proper use of a gift should show gratitude to and promote faith in God. (D&C 20: 27.)
Second, as to modalities:
I do think that there are aids to faith that can help someone who is weak to still act in faith. Modalities that focus thought, bolster confidence and assist in believing the Lord can heal can aid in the process. In the end it is the authority of God and faith in Him that allows good things to follow. It comes from Him. If an act helps focus thought and confidence in Him, then the act is worthwhile.
The problems creep in when the modality is regarded as an independent authority apart from God. As soon as a person begins to view God as uninvolved, or that they can control the outcome independent of God’s will, there is an opening for evil or deception. Gifts were not intended to produce a monetary profit and should not be practiced for money. (Acts 8: 20.)
Gifts belong to the body of believers and should be used to promote faith in God. (D&C 46: 10, 26.)
