He destroys himself, becoming arrogant and an apostate. And in the final analysis, his wealth will deceive him. He is seeking after money so that he can be happy, but happiness will elude him. His wealth will only give him anxiety, not contentment or security. The definition of a truly good life does not mean having maximum money.
Some people are overjoyed when they receive one hundred dollars.
Here Jesus is saying that you could gain the whole world, with all its power and money, but if you lose your soul, you have lost everything. It is a life that is vitally connected to God. A good life is a life of rest in God. By nature our hearts are restless, but we can never find rest with money, sex, pleasures, and things. Our hearts are restless until they find rest in God.
