How does Jesus' sacrifice affect our access to God?

Jesus' sacrificial death on the cross fundamentally alters how believers relate to God, granting them direct access to the Father. As observed in Hebrews 10:19-20, His blood creates a new and living way for us to enter the holiest of holies. The sermon illustrates that through Christ, we no longer approach God with fear or as outsiders, but as His adopted children who can cry out 'Abba, Father' (Romans 8:15). This means that believers can approach God confidently, assured of His love and responsiveness to our petitions, thanks to Christ's intercession and righteousness.
