People come into your life for a reason, a season or a lifetime. When you figure out which one it is, you will know what to do for each person.
When someone is in your life for a REASON, it is usually to meet a need you have expressed. They have come to assist you through a difficulty; to provide you with guidance and support; to aid you physically, emotionally or spiritually.
They may seem like a godsend, and they are.... They are there for the reason you need them to be.
