Sometimes what we say in words can achieve much more than a spiritual act of prayer

We, as humans have a power, not "the power", but a power to heal the people around us. the closest to the further st of them by our love and wisdom. real love is wise and wisdom radiates love.

What we say and do can speak volumes in peoples lives. If you take the scenario were a father left the home and the children were young. This changes the life of the young one forever. This point in their lives will probably determine how they relate to men, woman, themselves, issues of self esteem and identity issues.
When a father leaves, the child could either see it as their fault and there for see it as a rejection. "My father left because he didnt love me, it's my fault..."etc. The opposite reaction could occur when the young one just decides, as a result of the father leaving, that people are mean,evil, they are not trust worthy. And in their adult life, they may grow up with bitterness and resentment. Never able to trust anyone and essential believe that they are alone in this world. Or they may grow up with identity issues, always changing who they are to please people, or even sleeping around with different men/woman to receive a sense of love, or acceptance, or being wanted.

Now all this is a result of one mans action and maybe a few words which were repeated.
So if this one negative action results in such a reaction... this says something about the power that people have. Which may be more powerful than a spiritual act.
LOVE is the most powerful of acts. The abundance of will bring life and the lack of will bring death or sense of mourning.

If the someone you love is rejecting you, or if you want to make a difference in someone's life and all your efforts are not resulting in anything much, then change your approach! Dont inflict your language or expectation on them but, learn their language of love ;)
