The word "self-control" does not appear in these verses, but its lack is a major part of these women's problem. Their exact problem is unknown, but what we see here makes a good illustration.
Many modern versions change "the knowledge" in verse 7 to "acknowledge." Spiros Zodhiates says regarding this Greek word, "In the New Testament, it often refers to knowledge which very powerfully influences the form of religious life, a knowledge laying claim to personal involvement." Put another way, this word indicates not mere agreement with or admission of truth newly found but of truth already affecting the seeker's life. The knowledge these women received was not affecting their lives for the better.
Our challenge in life is not to become a tremendous reservoir of information that indeed may be true, but to control and rightly use what we already have while continuing to seek yet more. We acknowledge truth only when we use it in our lives, something these ladies were not doing. Considering the flood of information we have at our fingertips in this computer age, it is vital for us to understand that God judges us according to how well we use what we have.
