(Pro 30:12 KJV) There is a generation that are pure in their own eyes, and yet is not washed from their filthiness.
I like the way the KJV uses “generation” (1755) instead of the “kind” of the NASB. We talk about the baby boomers and millennials. Each one has some general tendencies. Each has those outside the box. So maybe it is safe to use the NASB translation because the tendency to be self centered goes beyond when you were born or how old you are.
With a toddler in our house the self-centeredness is very clear. We often joke about how original sin is rearing its ugly head. The newborn is even worse. The world must stop when the diaper is wet. There is no negotiation, only changes. Some people are like this. Actually all of us are like this until “washed” (7364) by the blood of the Lamb.
So? We can learn to control the self-centeredness of life but we will never overcome it until God does a great work in us.
