How much do you think you are worth?  The value of anything is determined by the price it will attract.  So, the value of a human soul is measured by what God is willing to give to purchase it.  The answer should stagger us.  God the Father was willing to give His own Son's life so that we might belong to Him (John 3:16).  

Many believers in Christ feel apprehensive about their safety as they face many dangers.  The Apostle Paul experienced those emotions too (2 Corinthians 7:5).  But unresolved, the door is open to two unasked questions, ‘How safe am I in Jesus?’, or ‘What do I have to do to make sure that God still loves me?’ Humanly, we do not feel worthy of His love (and we are not, it only comes to us by His grace).  And therefore we can easily slip into a religion of works, believing that if we do the right things then He will love us more - and that is not Biblical either.

Romans 9-11 especially focus on God's promises to His ancient people of Israel.  Although the first believers were all Jews, the Apostle Paul is sad that most of the Jewish nation did not connect God's Word or covenant promises with Jesus.  Although Christ was a human descendant of King David, most Jews resisted Him.  Indeed, the Apostle Paul had done the same until his conversion (Galatians 1:13-14).  But since then, he could clearly see how Christ Jesus fulfilled the Old Testament promises (Romans 1:1-6).

It should be obvious, but because God is so much greater than us in every way, it should not surprise us that we cannot fully understand all He does or why He does it.  In the same way that small children have no real understanding of global economics, but they trust food and clothing will be provided, so we do not need to grasp how God is bringing all things together for our good (Romans 8:28) under Christ (Ephesians 1:10).
