Parents love to remember the developmental milestones of their children. They will record in a baby book when their little ones first roll over, then crawl, and take their first steps. Often they will take photographs and save baby clothing to bring back the memories of those precious experiences.
According to Luke 2:19, Mary, the mother of Jesus, kept a baby book of sorts—in her heart. She treasured the promises that had been given about her Son and “pondered them.” The Greek word for “ponder” means “placing together for comparison.” Mary had heard of great things concerning her Son from angels and shepherds (1:32; 2:17-18). As His life unfolded, she would compare those promises with how her Son acted to fulfill them.
Our faith will be strengthened and we will be encouraged when we meditate on what the Scriptures say about God and compare it with the way He works in our own lives (John 14:21). He is a God who answers prayer (1 John 5:14-15), comforts us in our suffering (2 Cor. 1:3-4), and provides for our needs (Phil. 4:19).
When we take time to ponder, we will see the faithfulness of our great God.
God gives by promise that we may take by faith. (RBC)
