Spirit and in truth

Reading the Samaritan women in John 4 is so familiar. I can safely say that I grew up with it as a christian and thought I well understood this passage well. so here a chance for me to become humble and see where God takes me through this passage.
a Phrase caught my attention while reading:
"God is spirit, and his worshipers must worship in spirit and in truth" v24
At first, I thought, that make sense. but later on it didn't quit click. What does it mean to really worship in spirit? does it mean just the feeling of worship?
There I did little investigation of this and found a cross reference to Phil 3:3
"For it is we who are the circumcision, we who worship by the Spirit of God, who glory in Christ Jesus, and who put no confidence in the flesh—"
So I think worshiping in spirit does not mean it a mere feeling. not to say 'feeling' is wrong but that not the whole scope of it mean to worship in spirit. If we continue on this passage in Phil Paul is saying every thing he though he had gain by his flesh (himself and works) it consider lost. all he has done and is able to boost about it is long gone because of the surpassing work of Christ in him (Phil 3:7-10). he wanted to know and be like Christ. It's like the kingdom of heaven is like a treasure parable. A real worshiper in spirit and in truth is like living everyday, allowing God to work in you, to allow your everything you do become worship, when you eat, do your homework, interact with others, what you are thinking etc. It's not about you doing worship everyday but allowing God to take control in everything you do and it becomes worship. This is hard to do but nothing it impossible in Christ.

For God did not give you a heart of timidity, but a spirit of power, of love and of self discipline-2 Tim 7
