1 Timothy 5:6

‘But she who gives herself to pleasure is dead while she lives.’

As this is in contrast with the widow who regular attends daily prayer, ‘giving herself to pleasure’ probably indicates a lack of willingness to join the church in prayer, which could only indicate that she was busy with seeking other kinds of pleasure elsewhere. Such revealed that they were spiritually dead (compare James 2:17). It does not necessarily refer to what we would call ‘illicit pleasure’. The point was rather that she did not exhibit signs of spiritual life by regularly meeting up with the church. The early church had high standards (se Acts 2:46). For the idea of being dead while still alive compare Romans 7:10; Romans 7:24.
