Why is faith important for justification?

Faith plays a crucial role in justification according to Scripture. It is not the cause of our justification but is the instrument by which we receive it. Ephesians 2:8-9 emphasizes that we are saved by grace through faith, illustrating that justification is granted to those who believe in Christ as their Savior. This faith, which is itself a gift from God, allows believers to rest in Christ who has accomplished our righteousness. Therefore, while we cannot earn justification through works, faith is essential as it demonstrates trust in Christ's work.
