Walk in wisdom toward them that are without.
Life is far more complex now than it used to be. The pace of life is much faster than it used to be. More and more people are turning their backs on God. We desperately need to walk with wisdom. The only source of true wisdom is God. So each of us needs, on a daily basis, to ask the Lord for wisdom so that we will know how to treat the unsaved, when to speak for the Lord, how to act before the world, and in general demonstrate (without acting proud or giving offense) that we belong to heaven.
