Would you trust a brick building put together with mush as the mortar? Sounds ridiculous, doesn't it? No matter how solid the bricks, the successful binding together of those individual bricks to produce a strong structure can only be in proportion to the integrity of the mortar. And if every single brick is not produced with the same degree of integrity, the entire building could be weakened.
Is a civilization, a nation, or even a family any different? The strength of any of these depends on the "cement" of integrity. Unimpaired, pure, flawless, whole, morally sound—that's integrity.
We each possess that integrity from the very nature of our true identity. The opening chapter of the Bible records the actual nature of man as the image and likeness of God. And we all are capable of expressing our true selfhood.
