The concept of adequacy accompanies every practical aspect of our lives and states the existence of the necessary supplies and goods to achieve my goal; the sufficiency of goods and the sufficiency of all kinds of supplies to satisfy my future needs so that I do not find myself in deprivation and sin, that is, failure.
With this term of adequacy, Christ himself characterizes the parable of the ten virgins, that portion of the women who succeeded in entering the marriage simply because they had a sufficient supply of oil in their lamps.
The young virgins, not only have been struggling through the night to look for a store to buy oil, obviously at a higher price, but also have been ruled out in the most categorical manner of entering the fest. So when the ten started together, in the end, only those who had ensured the sufficiency and the excess of oil accomplished their goal.
The sin of the foolish was not moral but bad or non-existent calculation of the necessary supplies. The elements of indisputable love and the genuine interest they had for the bridegroom were not enough to open the entrance door of the new life.
