What to expect from R&R
– To deeply understand, believe, and enjoy the Gospel, and know who I am
– To be able to have any question answered without judgment. For example, “Why am I struggling so much even though I have faith?” and “If I seek psychiatric treatment, does that mean my faith is small?”
– To experience the ability to fight the spiritual battle in life, especially regarding mental health struggles around me
– If Jesus is the Christ who solved my fundamental spiritual problem that led to all the “bad fruits” of life, then He is the answer to any other problem (mental and/or physical) that I may face on this earth.
