How can I find peace in my spiritual life?

The source of peace for a Christian is rooted in understanding that Christ has accomplished all that is required for salvation. The gospel is not a call to do more but to rest in what has already been done. Believers can find peace through the assurance that their sins are forgiven and that they are accepted by God through faith in Christ. This peace surpasses understanding and guards our hearts, reassuring us that despite life's struggles, our ultimate security lies in the relationship we have with our Savior.
