You need to study the Bible instead of the philosophy of men that has deceived so many since Constantine got politics involved in Christianity.
1 Corinthians 3:12-15
12 Now if any man builds upon the foundation with gold, silver, precious stones, wood, hay, straw, 13 each man's work will become evident; for the day will show it, because it is to be revealed with fire; and the fire itself will test the quality of each man's work. 14 If any man's work which he has built upon it remains, he shall receive a reward. 15 If any man's work is burned up, he shall suffer loss; but he himself shall be saved, yet so as through fire. NAS
No place in Scripture is man's soul compared to gold.
The only part of your post that is true is nothing unclean will enter heaven:
Hebrews 9:23-28
23 Therefore it was necessary for the copies of the things in the heavens to be cleansed with these, but the heavenly things themselves with better sacrifices than these. 24 For Christ did not enter a holy place made with hands, a mere copy of the true one, but into heaven itself, now to appear in the presence of God for us; 25 nor was it that He should offer Himself often, as the high priest enters the holy place year by year with blood not his own. 26 Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been manifested to put away sin by the sacrifice of Himself. 27 And inasmuch as it is appointed for men to die once and after this comes judgment, 28 so Christ also, having been offered once to bear the sins of many, shall appear a second time for salvation without reference to sin, to those who eagerly await Him. NAS
Revelation 21:6-8
6 And He said to me, "It is done. I am the Alpha and the Omega, the beginning and the end. I will give to the one who thirsts from the spring of the water of life without cost. 7 "He who overcomes shall inherit these things, and I will be his God and he will be My son. 8 "But for the cowardly and unbelieving and abominable and murderers and immoral persons and sorcerers and idolaters and all liars, their part will be in the lake that burns with fire and brimstone, which is the second death."
NAS
Revelation 21:25-27
25 And in the daytime (for there shall be no night there) its gates shall never be closed; 26 and they shall bring the glory and the honor of the nations into it; 27 and nothing unclean and no one who practices abomination and lying, shall ever come into it, but only those whose names are written in the Lamb's book of life. NAS
