Whisk the lime juice, olive oil, chili powder, sage, oregano, and cumin together in a small bowl. Arrange the chicken breasts in a shallow glass container; pour the lime juice marinade over the chicken. Cover the container with plastic wrap; refrigerate 1 1/2 hours, turning the chicken every 30 minutes.
Preheat an outdoor grill for medium heat and lightly oil the grate. Remove the chicken to a platter and allow to come to room temperature. Pour the marinade into a small saucepan and bring to a boil over high heat. Reduce heat to medium-low and simmer for 10 minutes.
Basting with the marinade, grill the chicken breasts until no longer pink in the center and the juices run clear, 8 to 10 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
