“His mercy extends to those who fear him, from generation to generation. He has performed mighty deeds with his arm; he has scattered those who are proud in their inmost thoughts.”
God created us to glorify Himself. When people submit to God's authority, they can rest in the knowledge that God will sustain them. After 400 years of slavery, God delivered the Israelites from the Egyptians, and they thanked Him by building a golden calf to worship instead. The first commandment that Moses received states that God's people are to have no other gods. The Lord seems to be saying, "If I can't have you, no one else can." When humanity found no satisfaction on earth, they attempted to create a staircase to heaven, which resulted in God scattering the nations and changing their languages. Mary speaks of God scattering the proud; the people who displaced God.
Another translation of the Hebrew word for "scatter" is "to break up." I imagine someone who knows they made a mistake explaining that they are "really broken up about it." This image brings to mind 2 Corinthians 7:10; "For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death." God is jealous for the love of His people, and He will call our attention back to Himself no matter what it takes. Mary sings praise to God not because He has bestowed His unmerited favor to her but because He is the God who extends mercy to ALL who fear Him.
"GOD IS JEALOUS FOR THE LOVE OF HIS PEOPLE, AND HE WILL CALL OUR ATTENTION BACK TO HIMSELF NO MATTER WHAT IT TAKES."
LORD, you are my God. Thank you for the mighty ways that you display your extravagant love for me. Thank you for never forgetting your people and for always acting mercifully towards your humble servants. Please rid me of my pride so I may experience the fullness of joy that results from trusting you with my whole heart.
