Take a plant as an example, it won't grow healthy unless you water it. Like our life in this world, we won't bloom with happiness unless we truly experienced pain and suffering. 
Without pain, how can you appreciate the happy things in you life? 
we can only feel the greatest happiness if we walked through great problems and sufferings..

Hope that helped. :)
