And I will very gladly spend and be spent for your souls ... 2 Corinthians 12:15
For someone else’s spiritual well-being.
For his or her salvation.
This is ministry. In simplest terms. At its core.
However, it’s not only the responsibility of those who have ministry as a vocation.
It is the responsibility of everyone who believes.
Matthew Henry compares it to being a candle, which is consumed to give light to others.
Be a candle. Shine your light.
