The book of Leviticus was part of the Mosaic Law. The Israelites of ancient times were gathered to hear the law and to obey the principles in the Law, but not all of them were priests or kings. The king was supposed to make copies of the Law, and yet he did not take part in the direction for the priests. The priests didn't take part in the direction for the king. Not every Israelite was a priest and not every Israelite was a king, but they all could read the Law and the Prophets and learn from it.
It is the same today.
No, it is not at all the same today. All Christians are anointed, born again kings and priests.
But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession - 1 Peter 2: 9
Just look at how many times Jesus offered it to whosoever.
Mat_7:24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
Mat_16:25 For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
Mat_18:4 Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
Mar_8:34 And when he had called the people unto him with his disciples also, he said unto them, Whosoever will come after me, let him deny himself, and take up his cross, and follow me.
Mar_8:35 For whosoever will save his life shall lose it; but whosoever shall lose his life for my sake and the gospel's, the same shall save it.
Mar_9:37 Whosoever shall receive one of such children in my name, receiveth me: and whosoever shall receive me, receiveth not me, but him that sent me.
Mar_10:15 Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child, he shall not enter therein.
Luk_6:47 Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like:
Luk_7:23 And blessed is he, whosoever shall not be offended in me.
Luk_9:24 For whosoever will save his life shall lose it: but whosoever will lose his life for my sake, the same shall save it.
Luk_12:8 Also I say unto you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God:
Luk_14:33 So likewise, whosoever he be of you that forsaketh not all that he hath, he cannot be my disciple.
Luk_18:17 Verily I say unto you, Whosoever shall not receive the kingdom of God as a little child shall in no wise enter therein.
Joh_3:15 That whosoever believeth in him should not perish, but have eternal life.
Joh_3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
Joh_4:14 But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.
Joh_12:46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.
Act_2:21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
Act_10:43 To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
Mt. 26: 27-28 plainly states that those who partake of the cup enter into an agreement "for the forgiveness of sins" ..... not a kingship, not a priesthood. That comes automatically after they get their sins forgiven by washing themselves clean in the blood covenant of the Lamb.
This is the ONLY hope taught by the apostles for the congregation of believers.. You are welcome to try and find a NT scripture that shows how you can get your sins forgive outside of the NC.....but there aren't any! Galatians 1: 8,9 says says that if a person preaches any other gospel other than what the apostles taught, they are double cursed.
You may be personally offended by that, but it is not slandering you. That is just the corective word of God. The word of God is supposed to be offensive when we are off track.
If you just want to be cursed for preaching a two tier salvation unknown to the apostles and drummed up by a man with a 7th grade education (becasue that is where you got it) go ahead. God will eventually let you have what you demand. Hopefully, it won't come to that.
But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed....if any man preach any other gospel unto you than that ye have received, let him be accursed. - Gal. 1: 8-9
