First thanks for the response. you asked several question with a final one at the end, so we'll start with the Last one first.
the Son of Man is not trodden under anyone's feet, it's the rebellious people who by their murmurings, unbelief, and idolatry provoked God as was in the wilderness. the term "trodden under feet" convey the idea of treat or regard with contempt.
at the time of the Lord Jesus was walking on this earth, the Gentile nation of Rome had no regard for any Messiah who would be KING, nor did some of the Jews. even as now the one's who reject the Messiah, and disowned as their King, and still continue in their rebellion, even unto this day. supportive scripture,
Luke 19:11 "And as they heard these things, he added and spake a parable, because he was nigh to Jerusalem, and because they thought that the kingdom of God should immediately appear.
Luke 19:12 "He said therefore, A certain nobleman went into a far country to receive for himself a kingdom, and to return.
Luke 19:13 "And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come.
Luke 19:14 "
But his citizens hated him, and sent a message after him, saying, We will not have this man to reign over us".
THESE ARE THE REBELLIOUS ONES WHO REJECTED THEIR "MESSIAH"/King then. and some still even today. the ones who regard the Lord Jesus with contempt. this can give you better understanding of the Kingdom of GOD in the parable of the ten pieces of money here in Luke.
now all thing has been put under his feet, but this, Psalms 110:1 and 1 Corinthians 15:25. Psalms 110:1 "A Psalm of David. The LORD said unto my Lord, Sit thou at my right hand,
until I make thine enemies thy footstool".
1 Corinthians 15:25 "For he must reign,
till he hath put all enemies under his feet.
1 Corinthians 15:26 "
The last enemy that shall be destroyed is death.
1 Corinthians 15:27 "
For he hath put all things under his feet. But when he saith, all things are put under him, it is manifest that
he is excepted, which did put all things under him.
1 Corinthians 15:28 "
And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him,
that God may be all in all.
see, we still have some rebels right now who reject the TRUTH of God. some by Igorance, others ... no excuse.
so all things are under his feet, and Psalms 110:1
is in effect even as we speak. and if you're in christ then all things are under your feet, (hence this GRACE PERIOD). as with the Gentiles, yes they are under his feet, this is evidence of the Roman Captian Cornelius, a centurion of the band called the Italian band. be it known that his LIFE is written in the BOOK of LIFE, yes, this Gentile who did not rebel or reject the word of God. for this Gospel must go into all the world. those who rebell will be trodden under foot of the Lord. I hope that helped you in the "trodden down". it's rebellious Jews and Gentiles, better known as unbelievers who will be trodden down.
now -as concerning the daily sacrifice, Christ put an end to that when he gave his life. and as for the temple it was desolated in 70 AD.
Hebrews 13:13 Let us go forth therefore unto him without the camp, bearing his reproach. (For we seek a city to come.)
all those legal ceremonies, and the curse, supportive scripture, Galatians 3:13 "Christ hath redeemed us
from the curse of the law,
being made a curse for us: for it is written, Cursed is every one that hangeth on a tree". THAT'S HIS REPROACH for us. that we might, as the apostle Peter said, 2 Peter 1:4 "Whereby are given unto us exceeding great and precious promises: that by these ye might be
partakers of the divine nature, having escaped the corruption that is in the world through lust".
see, JBF, God did everything for us, if one do not accept his offer of ETERNAL LIFE, then they are ETERNALLY without him, "outer darkness". this city.. New Jersulem, is our Inheritance we have been qualified to receive the promise of the eternal inheritance. The qualification is of Him, not from us. His death is effective with us through the eternal Spirit and that His entering into the holy of holies made a new "LIVING" way for us as the apostle Peter said, "be partakers of the divine nature", not of this creation (old), but of the new creation. Because of this,
we should not expect a physical, material inheritance but a spiritual one. for all of this is done away with, "all things become NEW. so a building of a 3rd. 4th. or even a 5th. temple will do no one no good. the Inheritance of the saints is a Spiritual one an everlasting one.
yes if you loose your
saviour, (jesus the Christ), yes, thenceforth good for nothing, no regard, but to be cast out, and to be trodden under foot of men. THIS IS WHAT i LOVE, listen Matthew 5:14 "
Ye are the light of the world. A city that is set on an hill cannot be hid". understand JBF if your light go out you can be rekindle...

ain't God good. you cannot loose with God.
hoped that answered your questions.
