What does the Bible say about doubt in faith?

Doubt is a common struggle for believers, yet the Bible reassures us that our faith rests on the completed work of Christ. Believers often experience doubt despite knowing that they are represented before God by Jesus Christ, our advocate. This knowledge should lead to peace, as all sins have been judged and atoned for in Christ's sacrifice on the cross. The reality of this act and its effect on our conscience is essential for overcoming doubt. Believers must see their sins as eternally settled through Christ's resurrection, which confirms that sin has been judged and peace can be found only through faith in this truth.
