How do we know the doctrine of boldness before God is true?

The doctrine of boldness before God is clearly articulated in Hebrews 10:19-22, which states that we can approach God with confidence because our sins have been completely dealt with through Christ’s sacrifice. The writer connects this idea with the assurance of faith, urging believers to draw near to God, not based on their merit but solely on the finished work of Jesus. This teaching is central to covenant theology, which highlights God’s promise to have a people who are justified and welcomed into His presence through Christ.
