That's a good question there, brother Chopper.
To me, I see this verse basically as a paraphrase of Luke 10:27
27 So he answered and said, “ ‘You shall love the Lord your God with all your heart, with all your soul, with all your strength, and with all your mind,’.../
In other words, total submission, total focus upon Him and reliance upon Him, being led of the spirit constantly. More than just loving Him but...showing up for work, there's work to be done!
To present oneself as a living sacrifice, is just like it sounds. This isn't something that we wait on God to come give us an anointing to do something, nor is it to go extreme with ones body and and start being anal about things not good for the body like smoking or wotnot. It is to,
present oneself (snip) to Him (which means go to Him...
When Jesus gave up the ghost, the veil was rent in two (torn in half,) allowing access to the Kingdom realm to all. No longer would it be an annual event with only the priest allowed to pass the veil into the presence of God. The veil was not torn in half so that God could come to us, but so that we could go to God...
How many of you brothers and sisters have ever walked through the veil? Or tried to?
He wants us to go to Him. To boldly approach the throne as it were. This is another way of saying quit the world and all of it's ways. 100%. Not to be a sunday Christian but a full time Christian. Doing nothing except looking to the Lord for guidance and instruction, about everything. We're talking full on Jesus freak all the time.
I gotta go to work today. Or do I? Have I inquired of the Lord of what shall we do today? (It seems like many people switch back and forth between the Lord and the world...at times, they pray, go to church, reach out to people, testify to people, etc., but then oh, it's time to go to work or whatever so they back burner the Lord and go deal with the world...not a good thing to do).
But it really needs to be full time so to speak. He is the Lord. He comes first, first first, not as much as possible, but first. Lord, what will thou have me to do today? Here am I, and my life belongs to you. What is your will today?
Before work. Before anything. My life is the Lords and what He wants to do today is more important than work. Even to kill me. Yet though He slay me will I trust Him...
I think the important thing in this is the present yourself to phrase. This tells us go to Him. Cross that veil. Approach HIM. Don't wait on Him, He's waiting on you.
Does that make sense brother?
