In life we go through many tribulations and Jesus himself told us about her saying:
John 16:33
33 These things I have spoken to you so that in me you may have peace. In the world you will have affliction; But trust, I have defeated the world.
(RVR1960).
Jesus did not say that we would not have afflictions on the contrary he did not warn them but also gave us hope by saying "but trust, I have overcome the world."
In this way it is understood that there is hope in God since despite the tribulations to which we are constantly subjected the mercy of God is in us already promised to trust Him because no one can overcome Him, that is, there is no tribulation or problem that I can go above God or bend it.
In the midst of the adversities that we go through many times we think that we are alone but it is not so. God has promised to be with us and He does not fail and although sometimes we feel alone God is faithful.
In God's faithfulness is his mercy that never fails or fails because if his mercy really did not reach us we would be destroyed and hopeless.
The mercy of God implies compassion towards a helpless people who suffer for mistakes or for sin or for the circumstances that society fosters.
God longs for us to also practice mercy with others and feel the pain of others like us so that we can help you.
The proud lack mercy for that reason God rejects the proud but a merciful heart is honorable to God.
