'Reality' in the Bible

But a time is coming and is already here when the true worshipers will worship the Father in spirit [from the heart, the inner self] and in truth; for the Father seeks such people to be His worshipers.

God is spirit [the Source of life, yet invisible to mankind], and those who worship Him must worship in spirit and truth.”

For the words which You gave Me I have given them; and they received and accepted them and truly understood [with confident assurance] that I came from You [from Your presence], and they believed [without any doubt] that You sent Me.
