Judges 13:1-5
"The angel of the LORD appeared to the woman and said to her, 'Behold, you are barren and have not borne children, but you shall conceive and bear a son."  Judges 13:3
The number of barren women who conceive after God's promise of a son intrigues me.  Sarah is the matriarch of this group.  Genesis 18:10-12 says she was incapable of having children.  When the LORD promised her a son she laughed and thought "I am worn out, and my lord is old, shall I have pleasure?"  In Genesis 21:6, when the birth of Isaac fulfilled God's promise, Sarah said, "God has made laughter for me; everyone who hears will laugh over me." 
There are several other women besides Manoah's wife who were unable to have children until God blessed them: Rebekah (Genesis 25:20-21), Rachael (Genesis 30:22), Hannah (1 Samuel 1:2-5), and the Shunammite woman (2 Kings 4:13-17).   
At first glance, Elizabeth appears to be the last of this line of women.  In Luke 1, Zechariah is promised by an angel of the Lord, that Elizabeth will have a son even though she is both barren and beyond childbearing years.  Just as God promised, Elizabeth and Zechariah had a son, John the Baptist.  But the most magnificent miracle child is obviously Jesus.  His birth, just as promised, didn't even require a man. 
According to Scripture, there are also other "miracle children."  In Galatians Paul discusses the adoption of God.  Galatians 4:22-31 compares children born of the flesh to children born of the promise.  Galatians 4:28 has this incredible statement, "Now you brothers, like Isaac, are children of promise."  So, there are numerous "miracle children."  Everyone born of God (John 1:12-13) is a miracle child of the promise.
Interesting footnote, this miracle child, Samson, would "begin to save Israel." Jesus has since come to be not only the Savior of Israel but all the children of the promise.
Lord God, thank You for the promise of the Messiah for we know He is truly the Savior of the world.  We are as much, if not more, of a miracle child as Isaac, Samson, or John.  For Your glory and kingdom, may we fulfill the purpose of Your miraculous new birth.  Help us, Your children.   
Acts 17:26-28
How sovereign is the Lord God of heaven and earth?  What is the limit of His authority and power?  "From one man he made every nation of men, that they should inhabit the whole earth; and he determined the times set for them and the exact places where they should live." (NIV)
Wow!  God predetermined the existence of every nation, when it would rise and fall, and where it would reside.  Not only that but "In him, we live and move and have our being."  He determines not only these things for the nations of the world, but individually each of us is dependent on him for our life, our movement, and our existence.
Sovereign LORD, God Almighty, forgive me for detracting, diminishing and discounting Your authority in any way.  There is no One like You.  Singularly You rule and reign.  Please, may that be the truth of my heart and life.  I desire that nothing in my life be above or before You.
