Ability

a-bil'-i-ti (dunamis, or ischus): Variously used of resources, material, mental and spiritual; e.g. of wealth, "gave after their ability" (Ezr 2:69); of mental endowment, "ability to stand in the king's palace" (Da 1:4); of talents and character, "several ability" (Mt 25:15); of spiritual strength, "minister, as of the ability which God giveth" (the King James Version 1 Pet 4:11). It thus may signify either possessions, native capacity, or gifts of the Holy Spirit.
