1. 1 Thessalonians 5:16 In order to carry out the regulations given in vv. 12-15, Christians need personal communion with God. They are to be joyful always (see Mt 5:11-12; Acts 5:41; 16:25; Phil 1:18; 4:4). Indeed, they are to be “sorrowful, and yet . . . always rejoicing” (2 Cor 6:10). However, this Christian joy does not depend on earthly circumstances or feelings. It stems from what Jesus has done for us supernaturally, which never goes away.
   At the same time, Christians are to be constant in prayer. It is vital for them to lift the heart to God while being occupied with their duties. Concerning prayer, see 1 Thes 1:3; 2:13; Rom 1:9-10; Eph 6:18; Col 1:3; 2 Tim 1:3.
   Finally, Christians are to give thanks in all circumstances. Regardless of their human situation, they know that God has called them to eternal salvation and gives them the grace to attain it. Therefore, no matter what the circumstances may be, they can remain in a state of thankfulness (see Eph 5:20).
2. 1 Thessalonians 5:19 Paul now speaks about the responsibilities in communal worship. Christians must never extinguish the Spirit (v. 19). He is probably referring to curbing the charisms in any way. Guiding the charisms is necessary, but overcontrol is detrimental. In particular, the gift of prophecy must be esteemed properly and all charismatic manifestations must be duly tested. Any evil that tries to mask itself as a genuine representation of the Spirit must be discarded. Only then can worship be true.
