First, "always be rejoicing." (1 Thessalonians 5: 16) The students can gain joy  - which will fuel their enthusiasm  - by meditating on the blessing of being approved by Jehovah.
Okokuqala, "jabulani ngaso sonke isikhathi." (1 Thesalonika 5:16) Abafundi bangathola injabulo - ezovuthela intshiseko yabo - ngokuzindla ngesibusiso sokwamukelwa uJehova.
