Firstly, i am not going to say that Sunday is a less important day of the week. It's the day we honor the Sabbath, though orthodoxically the Sabbath falls on a Saturday, not a Sunday. Then again, Easter and Christmas don't fall on the days of Christ's birth or resurrection; those are merely when we observe them.
I understand the importance of observation, and that Sundays, being the day we honor the Sabbath, are important.
So without further ado, carrying on.
I want to bring to mind a certain fellow from the New Testament, perhaps the last of the Old Testament prophets. To know what i mean by "Old Testament prophets," those that lived before Christ were often the sort that lived as recluses, living outside of society, in hills, wildernesses, and the like. They were revered, probably even feared by some for their seeming mystical lifestyle and nature. They didn't dress nice, they didn't eat the same things as everybody else; they lived by the provision of God, and relied only on it. They could've taken to fame and grew in wealth, but they did just the opposite. Above all else, they knew who they were in God. They spoke with no authority of their own, but rather said "This is what the Lord says," invoking nothing of their own but rather the words God had given them.
And John the Baptist was of this lot.
He knew who he was, what God called him to, and set himself on (or rather, was called to) the same path as these prophets; "A voice of one calling in the wilderness, 'Prepare the way for the Lord, make straight paths for Him.'".
He was a prophet who had been prophesied about.
We are not called to simply live good on Sundays. I'm not talking about smoking, cussing, drinking; i'm talking about living as though God was alive in your heart!
We are a bipolar Church. We raise our hands on Sunday morning, we go up front for prayer, we may even shed tears, enough to fill a well, but come Monday many seem to have forgotten it.
Consecration is not merely living good. It's living in faith. It's trusting in God's providence. It's having faith that, though we may be homeless, orphans, abused, alone, starving, that God has providence to get His will completed, be it in our rags, or in our riches. It is the casting off of everything society expects of us. It is living without shame, not being afraid to be seen as a strange mystic to someone who doesn't understand the power flowing through us from Christ. It is being renewed according to Romans 12:1-2, offering ourselves as a living sacrifice should our Father in Heaven decide we should be required to die for His name. It is losing all inhibition, abiding by every faintest conviction of behavior we may receive from the Holy Spirit. It's being radically compliant to the Word of God, seeing God's place for us in Scripture and stripping ourselves away until we are fashioned into His decrees, set down by His prophets.
Yes, one of the Ten Commandments is to remember the Sabbath to keep it holy. In context, it is a law regarding work, not behavior. We are not told to live holier on this day, nor are we told to be a bolder follower of Christ on this day. No, instead we are told that the Sabbath is our day of rest.
I would dare say it more important to live in a consecrated manner for six days and then be laxed on the one--but that would be a falsity. The only truly Christian way to live is seven days a week. To live as though we were inside of the church every single moment, because we are the Church. The Church meets at a building on Sundays. We call it the House of the Lord, but that term was for the Temple of God set up by David if i'm not mistaken. The House of the Lord is, since the tearing of the veil, the Temple of God, is within us. It inhabits the church building only when we, the Church, occupies it, and only by proxy then.
Our sin is not in treating the building as less than absolutely holy. It is in treating our daily life as somehow less sanctified.
You carry the Church with you on Sundays when you are at the meeting place we call church, and also Monday through Saturday as you work, shop, eat, play games, sleep, read, breathe; in all things, you are the living and breathing Church, the tangible Body of Christ to the world.
It is your consecration to behave that way.
Our commission is to make disciples of all the nations--but this commission begins within us. We are the nations, too. Make disciples of yourselves first.
We are each called to be the next John The Baptist, the one who cries out to all who pass by, "Prepare the way for the Lord, make straight paths for Him."
