The wise took oil in their vessels with their lamps. Matthew 25:4. AG 214.1
The two classes of watchers [in the parable of the ten virgins] represent the two classes who profess to be waiting for their Lord. They are called virgins because they profess a pure faith. By the lamps is represented the Word of God.... The oil is a symbol of the Holy Spirit.... AG 214.2
In the parable, all the ten virgins went out to meet the bridegroom. All had lamps and vessels for oil. For a time there was seen no difference between them. So with the church that lives just before Christ's second coming. All have a knowledge of the Scriptures. All have heard the message of Christ's near approach, and confidently expect His appearing. But as in the parable, so it is now. A time of waiting intervenes, faith is tried; and when the cry is heard, “Behold, the Bridegroom cometh; go ye out to meet him,” many are unready.... They are destitute of the Holy Spirit. Without the Spirit of God a knowledge of His Word is of no avail. The theory of truth, unaccompanied by the Holy Spirit, cannot quicken the soul or sanctify the heart.... Without the enlightenment of the Spirit, men will not be able to distinguish truth from error, and they will fall under the masterful temptations of Satan.... AG 214.3
The grace of God has been freely offered to every soul.... But character is not transferable. No man can believe for another.... No man can impart to another the character which is the fruit of the Spirit's working.... AG 214.4
We cannot be ready to meet the Lord by waking when the cry is heard, “Behold, the Bridegroom!” and then gathering up our empty lamps to have them replenished.... In the parable the wise virgins had oil in their vessels with their lamps. Their light burned with undimmed flame through the night of watching.... So the followers of Christ are to shed light into the darkness of the world. Through the Holy Spirit, God's word is a light as it becomes a transforming power in the life of the receiver. By implanting in their hearts the principles of His word, the Holy Spirit develops in men the attributes of God. The light of His glory—His character—is to shine forth in His followers.69Christ's Object Lessons, 406-414. AG 214.5
Ask God to give you much of the oil of His grace.70Testimonies to Ministers and Gospel Workers, 104. AG 214.6
