En bref
Jesus reacts to the temptation to throw himself down by affirming his trust in his Father, and so refusing to test his Father’s promise.
Jesus does not even respond to the temptation itself, because he fully trusts in his Father, and trying to prove and test his Father’s care for him by such an act would in itself be a sure sign of a lack of faith and trust. This temptation was, after all, ultimately aimed at disturbing the relationship between Jesus and the Father.1
6 et lui dit: Si tu es Fils de Dieu, jette-toi en bas; car il est écrit:Il donnera des ordres à ses anges à ton sujet;Et ils te porteront sur les mains,De peur que ton pied ne heurte contre une pierre.
