Translation: 
Anyone who thus engages in the devotional service of the Lord, seriously and sincerely, with his mind, words and body, and who is fixed in the activities of the prescribed devotional methods, is blessed by the Lord according to his desire. If a devotee desires material religiosity, economic development, sense gratification or liberation from the material world, he is awarded these results.
Purport: 

Devotional service is so potent that one who renders devotional service can receive whatever he likes as a benediction from the Supreme Personality of Godhead. The conditioned souls are very much attached to the material world, and thus by performing religious rites they want the material benefits known as dharma and artha.
