We go into His Presence because of his clean record, not ours. His sacrifice cleansed us perfectly so we are never separated from Him ever again.
“But our High Priest offered himself to God as a single sacrifice for sins, good for all time. Then he sat down in the place of honor at God’s right hand. For by that one offering he forever made perfect those who are being made holy.” Hebrews 10:12, 14 NLT
“And so, dear brothers and sisters, we can boldly enter heaven’s Most Holy Place because of the blood of Jesus. By his death, Jesus opened a new and life-giving way through the curtain into the Most Holy Place. And since we have a great High Priest who rules over God’s house, let us go right into the presence of God with sincere hearts fully trusting him. For our guilty consciences have been sprinkled with Christ’s blood to make us clean, and our bodies have been washed with pure water.” Hebrews 10:19-22 NLT
