According to Irenaeus, what must humans do to reach their potential?

Irenaeus, an early Church Father, emphasized the importance of human experience, particularly the role of free will and the necessity of responding to challenges, including evil and suffering, as integral to spiritual growth and reaching one's potential. According to his theodicy, humanity is in a developmental stage where encountering difficulties serves a purpose. By facing and responding to evil, individuals develop virtues such as courage, patience, and compassion. This belief underscores the idea that growth comes from overcoming adversity, which is a central tenet of Irenaeus's thought. Therefore, reacting to and engaging with evil is essential for humans to fulfill their potential and achieve a deeper understanding of God and themselves.
