We have a purpose in life, and this purpose is that we all should live and do good. That is our major purpose in life. There is nothing else about life that supersede that. We came into this world to live and to fulfill our purpose in life, which our major purpose is to do good.
If you don't do good with your life, then the purpose of God in you is not fulfilled. God want us to live and declares His purpose.
People often ask, how do you do good to other people, even when in difficult times? this question somehow is striking. Because, while I was still listening to this teaching from the servant of God, the person who sat closed to me just asked the question, "How do we do good to other people, even in difficult times?".
Now God knew before now that sometimes will be difficult, but He still instructed us to do good. Why? Because our lives is of God and he always create and avenue or a condition that allows us to do good even in difficult times.
like when the servant says; that how we know the right time is when the situation allow you to do good. So, always do good, it is the will of God for humanity.
