A number of years ago Henry Drummond wrote a classic sermon titled "The Greatest Thing in the World." He concluded his sermon by suggesting that if you put a piece of iron in the presence of an electrified field, that piece of iron itself will become electrified. And in the presence of that electrical field, it is changed into a magnet. As long as it remains in contact with that field of power, it will continue to attract other pieces to itself. We are like that piece of iron. In the presence of Christ, we experience his love and take on his likeness. We are changed, electrified by the Holy Spirit, to attract others to the same love of God that we experience.
