, it is important to remember that preaching typically involves more than just talking about God. Preaching often includes sharing Biblical teachings, offering guidance and encouragement based on Scripture, and providing spiritual insight to others. While a 12-year-old may have a strong faith and be able to share their beliefs with others, they may not have the knowledge or experience to effectively preach in a formal sense. It is always important to consider the context and audience when discussing matters of faith and spirituality.
