A change has already occurred in the way we approach God In righteousness. Now it will bring a reformation in the way that you approach God. In the Old Testament man, because of his fallen nature, could not approach God because that sin worked death in man. God and sin can’t be on the same plane. That’s why we needed a Savior that could wash away our sins. Then we could have time to develop walking in Holiness and righteousness before him with out the wages of that sin hanging over our heads. For the wages of sin is death, but the gift of God is eternal life through Christ Jesus. Romans 6:23
Throughout your Faith, you must believe the report. In doing so, your conscience will be clean, it will be purged of that dread of punishment. Then as your walking uprightly before God through Christ Jesus, you can just jump up into his lap and talk to him as a child would talk to his parent. This was God’s plan from the beginning
Hebrews 9:6-10
6 Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God. 7 But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people: 8 The Holy Ghost this signifying, that the way into the holiest of all was not yet made manifest, while as the first tabernacle was yet standing: 9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience; 10 Which stood only in meats and drinks, and divers washings, and carnal ordinances, imposed on them until the time of reformation.
