To be called is to have a reason for existence

God and His kingdom are the reason for our existence

You are called to do a certain work – do it

The worse scenario is when you do not know the purpose of your day to day existence

Always find purpose in your existence

It is not enough to have a body to be qualified as a man. Animals too have bodies and we don’t call them man for some reasons – they don’t qualify. So such is man, such is human, who might not be qualified because he has not attained the height where he sees realities as God wants him to see it.
