Thoughts on Worship to GOD

I was thinking a lot today about what it means to worship in Spirit and in Truth... So it says in the Bible to love God with all your heart, all your mind and all your soul (Matt 22:37) so I suppose this is like saying Love God with everything in your body that can (Heart, mind and soul) and then in Romans 12:1 it says "Therefore, I urge you brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God-this is your Spiritual act of WORSHIP" So our spiritual act of worship is offer our bodies as sacrifices to God...Now what the flip does that mean... Bill Johnson says "fire always falls on sacrifice" and that worship is suppose to cost us, the lady with the alabaster jar (which was all that she had) that she spilt on Jesus and wipped his feet with, that cost her, it cost her her only source of money (selling the jar), it would of cost her the dignity (wipping Jesus's dirty feet with her hair and this oil). This act of worship was sacrifice, holy and pleasing to God.
I looked up what worship meant and it meant to prostrate yourself before God so to lie down before him (note: spell it right before you google it otherwise you get prostate cancer for men...) and to lie down on the ground, face on the floor before someone would be costing you a bit of dignity and it would be pretty much humbling yourself before someone bigger and better than you I suppose? That is why people would bow down before Kings in the towns back in the day.
The English dictionary meaning of worship is to be devoted to something/someone, so for us as Chrsitians it would be to be devoted to God, loving him with every part of our being and living pleasing and holy lives.
So that is our Spiritual act of worship, and to worship Him in truth, from what I understand that means to worship him in our actions, not just the songs we sing or the things we speak but to honour him in truth, in words. It says in the word that the word was God and that he is the way and the truth. So to worship Him in truth would be to worship him through the word and living out the word and living out the way he has called us to be?
