If not a Relationship then you are practicing a Religion, same as the Muslims and the Hindu's.
You can argue Religious Doctrines of what you believe or have been taught all day long and you will never know who Yahweh is.
Once you receive the Holy Spirit you have a Relationship with God. The Spirit of God is inside of you teaching you as a Father does his son. He talks to you and shows you how much the Father loves you.
Any communication develops into a Relationship.
No communication then NO Relationship.
No communication then NO Relationship then you are Lost and practicing a Religion.
