This reflects the universal nature of God's care and the importance of His messages for everyone.
It underscores the timelessness of God's word, suggesting that what was spoken in the past continues to hold relevance. This invites us to consider how ancient prophecies and divine messages can inform our lives today. By acknowledging that God's word has been spoken, we are encouraged to seek understanding and application of these teachings in our own contexts. This verse also serves as a call to humility, recognizing that God's wisdom and plans are far-reaching and often beyond our immediate comprehension. It encourages us to trust in His guidance and to be open to the lessons that His words impart.
