When Christ died, the Bible says “Now it was about the sixth hour, and there was darkness over all the earth until the ninth hour. Then the sun was darkened, and the veil of the temple was torn in two. And when Jesus had cried out with a loud voice, He said, “Father, ‘into Your hands I commit My spirit.’” Having said this, He breathed His last. So when the centurion saw what had happened, he glorified God, saying, “Certainly this was a righteous Man!” And the whole crowd who came together to that sight, seeing what had been done, beat their breasts and returned. But all His acquaintances, and the women who followed Him from Galilee, stood at a distance, watching these things.” (Luke 23:44-48)
The separation between God and man has been removed. All other major religions keep the veil up. Those that worship in those religions are not allowed to get close to their gods.. They must work and strive and labor to be like god, to get close to god, to transcend this world. But Christ is different. “Jesus spoke these words, lifted up His eyes to heaven, and said: ‘Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.’” (John 17:1-3) We have the right to be close to God. “Behold what manner of love the Father has bestowed on us, that we should be called children of God! Therefore the world does not know us, because it did not know Him.” (1 John 3:1) We no longer have to DO THINGS to be accepted. The cross tore down the veil. It ended the need for us to plead with God. We are now in the family of God. We are his children.
When we look at the role of the High Priest, we see the old way of approaching God. He was only allowed to come to God after he cleansed himself. Then he had to sacrifice to God. “For He Himself is our peace, who has made both one, and has broken down the middle wall of separation.” (Ephesians 2:14)
