Another word for thankfulness is appreciation, and the best way to show appreciation for any gift is to take care of it. This applies to spiritual gifts as well.
If we let our spiritual gifts fall into ruin through abuse or neglect, then we aren’t appreciating how fortunate we are to have them. Therefore, take some time every day to thank God for your many gifts. Use them as often as you can and to the best of your abilities. A spirit of appreciation is always accompanied by a great sense of joy and unity with God and those around you.
