"Difficulties are the greatest blessings of the God" Let's understand HOW?

Sometimes when you get caught up in a difficult situation and end up being in a great tragedy. You pray a lot but the end result didn’t come the way you wanted. You start questioning the faith and existence of God. You start blaming him for all the bad times in your life. When you need the blessings of our heavenly father the most, you cut the connection with him. You stop praying and asking for help because you think if he was there in the first place, this difficulty would not have come into your life.

This is the time you require the power, blessings, strength of God to overcome difficulties but instead you resist god to help you. Difficulties are the greatest blessings of god because at this time only, you realize your full potential and strength to come out of the bad times strongly. Earlier, where you use to think yourself weak, powerless and less than others, God gives you a chance to use your capabilities and inner strength to become the best version of yourselves. Pain is the greatest teacher. Every time, you face a challenging moment, you try to use all you have within to fight and overcome the problems. If you see carefully, every successful person was encountered with great difficulties and challenging period and to overcome them they used their god gifted talents, of which they were earlier unaware of. There is a lesson in every problem for you. Problems are not to break you but to help you find yourself. Self-realization is one of the reasons you are here on Earth.
