Theosis is a theological concept primarily found in Eastern Orthodox Christianity, referring to the process of becoming one with God or attaining divine likeness. It emphasizes the transformative journey of believers, where they grow in holiness and grace through their relationship with Jesus Christ and the Holy Spirit. This idea is rooted in the belief that humans are created in the image of God and can participate in His divine nature. Theosis is often associated with practices such as prayer, sacraments, and asceticism, which help individuals cultivate a deeper spiritual life and connection to the divine.
