Fullness refers to the state or condition of being full, complete, or filled with something. It can describe a sense of satisfaction and contentment that comes from having one's needs met or desires fulfilled. In a broader sense, it can also refer to an abundance or excess of something, such as a fullness of joy, love, or generosity. The word "fullness" is often used in religious contexts to describe the presence and power of God, or the idea that God's grace and blessings are overflowing in one's life.
