As Paul stated, I have learned to be content whatever the circumstances. I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. The key for Paul was an attitude of contentment. The problem for the rich young man was an unwillingness to give up the pleasure of wealth, which prevented him from becoming perfect.
Most humans virtually ignore the spiritual realm.
Those who acknowledge it frequently want to use it for personal gain through the occult, which promises control, influence, improved personal condition, and so on. The normal human condition is totally self-centered, so that you do things for others because it makes you feel good or promises to benefit you in the future. Your sinful nature motivates you to do everything for selfish reasons. In the least, that is an intensely lop- sided attitude. From God's perspective, however, such a person's attitude is divided, incomplete, inferior or blemished.
