You can only help others in proportion to what you yourself have suffered. The greater the price, the more you can help others. The lesser the price, the less you can help others. As you go through the fiery trials, the testings, the afflictions, the persecutions, the conflicts—
as you let the Holy Spirit work the dying of Jesus in you—life will flow out to others, even the life of Christ.
