In this lesson from the “All That Jesus Taught” series, we begin exploring the Sermon on the Mount (Matthew 5–7), focusing on the first three Beatitudes: being poor in spirit, mourning over sin, and walking in meekness. Jesus spoke these words primarily to His disciples, revealing the foundational attitudes required to possess the Kingdom of Heaven. Poverty of spirit is described as daily spiritual dependence on God; mourning is sorrow over sin and spiritual failure; and meekness is surrendering personal rights in humility. These qualities, perfectly demonstrated in Christ, form the true beginning of discipleship and the pathway to spiritual authority and fruitfulness.
