Ephesians 5:28-33 (Go to this verse :: Verse pop-up)
A baby is not born evil. It is most certainly born with a measure of self-centeredness that God pronounced as very good in Genesis 1:31, for some small measure of self-centeredness enables a person to take care of the self.
Understood and controlled, a right measure of self-love provides a foundation for the love of others, which proves beneficial for the giver as well as the receiver. This is especially true in marriage because husband and wife become one flesh; to love one's spouse is to love the self because of this oneness.
It is at least equally true, if not more so, in our relationship with Christ. He is our example. Because of our spiritual oneness with Him, and because we are His body, His loving service of us is the same as loving Himself. This principle works both ways. Our loving service of Him is also the same as loving ourselves. What we see in these two intimate relationships is a practical application and benefit of the Golden Rule—"Do unto others as you would have them do to you"—in operation, with the added benefit to the giver.
The problem with self-love is that, without contact with God throughout life, an individual's innate self-centeredness can easily develop into an extreme and sharply honed sinfulness and evil. Such an egotist gives little thought to loving others as a way of life; he shows little care for others and rarely looks for ways to serve. Without God, life becomes all about the self. The world, established by and built upon selfish human nature, continues to feed its self-absorbed inclinations and cravings.
