To have faith and trust in how you feel and to love one another

To have faith and trust in how you feel and to love one another
That is a very strong word "FAITH".  A word that means so much but can be forgotten in an instinct. As I was growing up I had no FAITH because I didn't believe in myself and I trusted no one. Yet I had friends but not ones that I can say that we have remained since elementary, junior high or even high school. You know those friendships that regardless what has happen in life you are still friends, till the end. Don't get me wrong I have friends now and very good friends but it is hard to teach your children about friendship when they come and go.
But I came to grips with something, that friendships are placed in your life for a reason. That people are placed in your life at the time of your needs. You are to learn from them, cry with them, grow with them and learn to forgive with them. That the higher power knows who are your real friends and it's not only friends, it can be your extended family too as your friends. So don't fret because people come in and out of your life it just means that the  friendship is done for now. It just means that it's time to move on to a next chapter. 
That is what I am trying to teach my children. Which is very hard for them to understand because todays times are so different from when I was growing up and times are so advance beyond.
