Luke chapter 02

19 But Mary treasured up all these things and pondered them in her heart. 

51 But his mother treasured all these things in her heart. 

Continuing my observation in Chapter 01, we can find that Mary often keeps preserving and reflecting on encounters and dialogues around her even though she is at moment unable to understand all of them. I think it's really a good habit of paying attention on every little messages from God and rethinking about them, which will improve our undersatnding of God.

Besides, continuing to compare Zechariah with Simeon and Anna, we can find their different basis of faith. As the description in chapter 1, Zechariah is "upright in the sight of God, observing all the Lord's commandments and regulations blamelessly.(1.6)" In other words, his faith is on the basis of laws but lack of the hope of God's promises. By contrast, Simeon is "righteous and devout. He was waiting for the consolation of Israel, and the Holy Spirit was upon him.(2.25)", and Anna also "spoke about the child to all who were looking forward to the redemption of Jerusalem.(2.38)". In this way, their faith is on the basis of hope and of waiting for those unseen. 

So we have to keep our faith living and always being thirst for God's promises, but not let it die in simpe obedience or routine services. Otherwise, that would be a great pity.
