“The peace of God” means peace above circumstances.
“The peace of Christ” (“My peace I give unto you”) means peace unmovable amidst circumstances.
“I shall not be moved,” and why? Because He has set His God before His face, and God was at His right hand.
“Yesterday” He loved me;
“Today” He’s just the “same.”
How long will it continue?
“Forever.” Praise His Name!
