Kierkegaard - Works of Love Chapter 4

Our duty to love those we see.

The need for love and the need to love are deeply embedded in the human nature.  This is visible in the need for community that we all share to some extent.  Most "religious" folks would also add there is a human need to love God.  A Christian has the added qualification that "anyone who says he loves God, but hates his brother ( fellow human )  is a liar."

Our duty is to love all those we see,  not to seek out those with lovable qualities and love them.  In other words our task is not to find the lovable object, but to find the object lovable.

Special Considerations:
If you want to show that your life is intended for service to God, then let it serve men. For God has indicated, if you love me, love the ones you see.

Those who call it misfortune that they have not found a lover  ( ie someone to love ) further prevent themselves from finding him or her since the do not understand the initial step.

If the duty is to be fulfilled, there is to be no double-mindedness about the lovers faults, weaknesses or imperfections. The love is limitless and unchanged regardless whether the object changes.  See for example Jesus love of Peter.  "when he no longer loves you, when he perhaps turns indifferent away to love someone else, love him as you see him when he betrays and denies you."
