John 4:24 God is spirit, and his worshipers must worship in the Spirit and in truth.
God is Holy. He is Just. He is not just something someone made up. God is real!
But we also need to know Him as being God the Father, God the Son and God the Holy Spirit.
Right now, we cannot see Him. God the Father is all encompassing and everywhere. God the Son, Jesus, is enjoying His time in Heaven. The Holy Spirit is here with us continually, even though we cannot see Him.
We need to worship our Great God as being the way, the truth and the life; everything in our lives!
