The phrase "god-given talent" is commonly used to describe a natural aptitude or skill that a person possesses. However, there are several synonyms that can be used in its place. One possibility is "innate ability," which refers to a talent that is present from birth and is not learned. Another term that can be used is "giftedness," which implies that the talent is something bestowed upon a person by a higher power. Additionally, the phrase "inherent skill" can be used to describe a talent that is a natural part of a person's being. These synonyms all convey the idea that a person has a particular talent or ability that is not something that can be taught or learned.
