God-centered relationships: Children and Parents. Servants and Masters. The Whole Armor of God.
(Here is an extract from Grok3 from Twitter: Daniel 10:13, Gabriel, an angel, mentions to Daniel that he was delayed because he was contending with the "prince of Persia," a spiritual entity, likely a demonic or supernatural being, influencing the Persian kingdom. Gabriel says he was detained for 21 days until Michael, another archangel, came to assist him. This passage highlights spiritual warfare, where angelic beings engage with opposing spiritual forces that influence earthly powers.)
