Devozine is a magazine and website that offers devotionals and more for teenagers. Most articles, stories, and devos shared are written by teens. Sometimes writing can be a great way for us to grow in our faith because it causes us to research, reflect, and think through that which we are writing. It invites us to learn and communicate in a way that encourages others on their spiritual journey. Writing can be a powerful way to share your story and thoughts with other teenagers who are in similar places in life as you. Consider writing as a spiritual practice and as a ministry
