"ABOUT FACE" is a common command in the military and signifies a complete reversal of direction AND is also an excellent description of repentance, a complete reversal in thinking which results in a complete reversal in one's behavior!
In the Old Testament, the phrase "but God" is used to highlight God's intervention and grace in seemingly hopeless situations, often appearing after a description of human failure or disaster, signifying that even when all seems lost, God will still act with mercy and bring about a positive outcome; it essentially conveys the idea that despite human limitations, God's power and love remain constant, offering hope and redemption.
