"See then that you walk circumspectly, not as fools but as wise, redeeming the time, because the days are evil." (Eph. 5:15-16) A footnote on "redeeming the time" in the ASV says, "Gr. buying up the opportunity."

"The idea is that we make the most of every opportunity. The word 'opportuntiy' comes from the Latin and means 'toward the port.' There is a familiar saying that 'if the pilot does not know which port he is headed for, no wind is the right wind.' If one walks wisely, he will not drift with the wind and tide, but he will give proper thought, make plans, and then set his sail!"
