‘Look therefore carefully how you walk, not as unwise but as wise, buying up the time because the days are evil.'
The Christian is to live a life of careful thought. He does not blunder blindly on but weighs up his life and makes the most of his time, ‘buying up the time', to bring the most glory to God. He makes sure that he walks in the light before God, and in these ‘evil days' ensures that his life is a force for the good. He walks as one of those who is truly wise, in contrast with the unwise.
