This is our human spirit. According to typology, God should be worshipped
1) in the place chosen by God for His habitation (Deut. 12:5, 11, 13-14, 18),
2) with the offerings (Lev. chap. 1—6). The place chosen by God for His habitation typifies the human spirit, where God's habitation is today (Eph. 2:22). The offerings typify Christ; Christ is the fulfillment and reality of all the offerings with which the people worshipped God. Hence, when the Lord instructed the woman to worship God the Spirit in spirit and truthfulness, He meant that she should contact God the Spirit in her spirit instead of in a specific location, and through Christ instead of with the offerings. Since Christ, as the reality that issues in the human virtue of truthfulness, has come (vv. 25-26), all the shadows and types are over.
