John 4:21-24

Jesus said to her, Woman, believe Me, a time is coming when you will worship the Father neither [merely] in this mountain nor [merely] in Jerusalem. You [Samaritans] do not know what you are worshiping [you worship what you do not comprehend]. We do know what we are worshiping [we worship what we have knowledge of and understand], for [after all] salvation comes from [among] the Jews. A time will come, however, indeed it is already here, when the true (genuine) worshipers will worship the Father in spirit and in truth (reality); for the Father is seeking just such people as these as His worshipers. God is a Spirit (a spiritual Being) and those who worship Him must worship Him in spirit and in truth (reality).
