The religion of the Spirit was the religion of Jesus, since God, his (our) Heavenly Father, is Spirit (Gospel Jn 4:24).
The Gospel is for divine filiation, the education and spiritual development of the mind and soul; consequently, pleasant self-control is acquired voluntarily and progressively; as well as fraternal coexistence among peers.
It is not about morality, condemnation or temporary beliefs.
Thank you, brother, and for me, after studying the magnificently perfect life of our Beloved Brother, Jesus, in the Revelation, his religion was a personal relationship with his/our Father, as evidenced in his desire to take time to quietly be with him...to understand his Will for his life here. As we need to do!
