Those who do are drawn in by the love that they feel from you. Those who do not, may not trust the love you are offering or they may perceive your efforts as weak or they may just hate the message, no matter how it is packaged. It is my opinion that the gentle approach should be used first, generally. If the response is negative, it may be beneficial to move to another style. Whatever your approach, you must always have a genuine love for the person and display such love openly.
Love can also be confrontational, tough and resolute.
If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing. Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
