How do we know salvation by faith in Christ is true?

Salvation is affirmed throughout Scripture, particularly in Romans 3:26, where it states that God is both just and the justifier of the one who has faith in Jesus. This teaches us that God's righteousness demands that sin be addressed, and it is only through the perfect sacrifice of Christ that we can be justified. The analogy of the Ark of the Covenant in 1 Chronicles illustrates how God's strict requirements in worship point to the need for a perfect mediator—Jesus Christ—who fulfills the law and provides the means for us to be reconciled to God.
