How does the Lord provide peace for believers?

In Psalm 23, it is stated that the Lord leads us beside still waters, symbolizing the profound peace found in Him. This peace is not dependent on external circumstances but rather rooted in the assurance that our sins are forgiven through Christ's atoning sacrifice. True peace comes from knowing we stand justified before God, free from the condemnation of sin. This peace surpasses all understanding, resting in the fact that the Lord, as our shepherd, manages our lives according to His sovereign will, offering comfort and serenity amid life's tumult.
