Well, I am the most optimistic and content/happy person many people know; at least that is what they have told me. It is not because of reformed theology, although I certainly believe that there are members of the CRC who are indeed happy and have no reason to doubt that you are one of those. That said, I went to a "'Mere Christianity' Worldview Weekend Conference" in which one of the presenters, obviously a Calvinist based on his statements and his 'Dutch' name (I actually confirmed this with him afterwards), stated that a Christian should not be 'happy' but should only experience 'joy'. I am happy to know that at least one reformed Calvinist agrees with me.
BTW, are you still CRC, or one of those 'apostate' Reformed Church members. LOL. There is a difference, as you must know. I know lots of Reformed Church people who are 'happy'.
Have a HAPPY day,
