Sentimental feelings about your religious heritage is not the same as a vital current relationship with God.  Religious and theological debates prove nothing about your spirituality.  What matters is a heart full of love brought by the abiding Spirit (John 17:26, Rom 5:5).  What matters is you being truly in the Lord and the Spirit of the Lord being truly in you (Jn 17:21).  This is what our heart craves.  This is the destination of our spiritual formation.

“The love of God has been poured out within our hearts through the Holy Spirit who was given to us.” Romans 5:5
