God had chosen, in His sovereign plan, to bless Leah with children while keeping Rachel barren for a time. Leah was aware that God is the one who was given her children. We should not count on something other than God's will. We should not be determined to get what we want, instead we should desire to seek and do the Lord's will. God is the one who opens and closes the womb. God gives and withholds the capacity to have children. God knows and calls us by name. The reason why God saves us is not because we have done anything. God makes people alive and He saves. The reason why God blessed Laban was not because of the divination that Laban used but because it is God who blessed him. God is the ruler of the Universe and He is the one who makes the rules. We are blessed, often times because of those who have gone before us. God blesses in spite of sin, not because of it. God alone can save and He knows exactly what He is up to.
