How do we know that God dwells in those who are poor in spirit?

The character of those in whom God dwells is marked by a recognition of their spiritual impoverishment. As articulated in the sermon, a person who is poor in spirit recognizes they have no merit before God and is utterly dependent on Him for their needs. This awareness is a work of the Holy Spirit, which cultivates in them a contrite heart that feels sin deeply and desires reconciliation with God. It is the Spirit that enables them to apprehend God's greatness and their lowliness, leading to a genuine faith that embraces God's grace.
