1 Thessalonians 5:6-8
6 Therefore let us not sleep, as others do, but let us watch and be [a]sober. 7 For those who sleep, sleep at night, and those who get drunk are drunk at night. 8 But let us who are of the day be sober, putting on the breastplate of faith and love, and as a helmet the hope of salvation.
Living a life of discipleship is their lifestyle and they live for the kingdom of God
