Living and Holy Sacrifices

I see all of the time people say that Christianity is not a religion (which is absolutely true) but a relationship (which is only partially true)... The Law held people to religious ways and actions to appease God. As also the false gods also instilled their own acts of religious worship towards them as counterfeit means to pacify them... Then in our daily lives we have different people that we have relationships with that we do not involve an intimacy with. Your employer or coworkers are a perfect example. You may have a respectful relationship with an employer as he is the one who manages the business and signs your paychecks, even though at time he may also be a womanizer, so therefore you don't have a friendly relationship with him because of his immorality. Same with coworkers, you work alongside them and even converse back and for in a relationship fashion, but when the clock strikes 5 o'clock, they go there way into some kind of debauchery while you go home to your loving family... You never have a relationship with any of these outside of your work place because they lead immoral lives ad you are leading into a sacred holy lifestyle...
In the Samuel, Isaiah, and Ezekiel God said that He desired obedience over sacrifices and the fat of rams. And also that people claim to His but truthfully they follow their own lustful desires out of their mouths and deeds... Then Jesus also quoted from Isaiah stating that though people profess God with their lips, their hearts are far from Him... The Old Testament and the Law were a physical means of atonement to adhere for short comings of following the complete of the Law which sin has came into the lives of men. Yet adherence to the Law was to be an outward showing of submitting to and following our Heaven Father, the One and Only God... With people only going through the physical motions but not worshiping God in Spirit nor in Truth... It does not take much of a look around today and see where many simply worship God through acts of religion (words) but their lips are far from Him (they only desire to fill their own bellies)...
Jesus took the letter of the law and fulfilled and nailed it to the cross as the final sacrifice for atonement for sins through the blood that poured out from Him... Jesus said that one must be Born Again in Spirit to see and enter the Kingdom of Heaven... Jesus said that God is Spirit and is looking for them who worship Him in Spirit and in Truth... The in Romans 12:1-2, we are told to offer our lives (as Jesus did) as living and holy sacrifices, which is our Spiritual act of Worship. Then do not once again conform to this world (sinful practices) but be transformed by renewing our minds ( transformed to be as Jesus )...
The title Christian was given to believers in Antioch who followed the ways of Jesus, they walked and talked in the same manners as Jesus, they were set apart from this world and its ways and were indeed living and walking in the Spirit of God...
