Happiness and joy, sadness and godly sorrow
Happiness comes from enjoying/experiencing and delighting in the good things/people of the world.
However, joy comes from enjoying/experiencing and delighting yourself in God or in His things. And no one can have joy without having a good relationship with God. For without a good relationship with God, how can you enjoy and delight yourself in Him?
This kind of joy seeks to stay closer to God
Sadness comes from experiencing the bad things/people of the world happened to you.
However, sorrow comes from undergoing the “bad” things happened to you from God or the bad feeling that you had committed things agasint God. This kind of sorrow brings yourself to be right before God so that you can have life.
This kind of godly sorrow seeks to reconcile with God.
Godly happiness is joy. While godly sadness means godly sorrow.
