Why the Old Testament is necessary for faith

People often wonder why the Old Testament is such a large part of the Bible?  Does it have any function, besides all the wars, intrigues and the ‘incomprehensible’ prophetic books?  The answer has to do with the Good News of God’s Kingdom. 

#  What is the Good News of the Bible?  

  • It is simply that we can become part of God’s Family through Jesus’ blood.  That means we become God’s blood relatives and will receive ‘an inheritance that can never perish, spoil or fade.’ 1
  • What will we inherit?  Eternal life, with God who loves us, on the new heaven and earth. 2  It will be a wonderful life of joy, peace and love with food, health, friendship, lodging, safety, et cetera.      
  • The issue is: how do we know that this glorious fantastic future will become a reality?  The answer is in the Old Testament.

#  The history of the Old  Testament explains the Good News. 

  • For example, we understand that Jesus was the Lamb of God who died on behalf of our sins, because the Old Testament tells us that a lamb was sacrificed for the sins of the people.  
  • We understand that Jesus, the last Adam, takes us back into God’s presence, because the Old Testament tells us the first Adam caused us all to be expelled from God’s presence.  
  • There are many more such explanations and also specific promises in the Old Testament that build our faith in God.

# Three Old Testament promises

  • God gave Adam and Eve a promise.  The Seed of the woman will crush the head of the serpent. 3  It refers to Jesus who was born of the virgin, Mary and who defeated the devil on the Cross. 4
  • God gave Abraham a promise.  Through him all people on earth will be blessed.5   It refers to one of Abraham’s specific descendants, Jesus.  He would be a blessing to all people. 6 
  • God gave David a promise.  His throne will endure forever. 7  It refers to King Jesus who sits on the throne at the right hand of the Father. 8  

#  The Old Testament shows God is faithful. 

  • God’s promises to Adam,  Abraham and David were fulfilled in the New Testament.  Without the Old Testament we wouldn’t know that God is completely trustworthy.  
  • He gave the promises, and despite the devil’s efforts to thwart those promises, they happened: Jesus was born, He was sacrificed on the Cross, He was resurrected.  Now He sits at the right hand of God the Father. 9  
  • The history of the Old Testament covers around 4,000 years.  Yet it all converged on Jesus, the focus of God’s plan.  If there was no Old Testament record, there was no reason to believe in Jesus or the Kingdom.

Conclusion

The Old Testament proves that God is dependable to the tee.  What He promises, will come to pass.  When God speaks in Scripture, it will happen.  That is why the Old Testament is such a large part of Scripture.  It gives us faith in God’s promises.

As you can see in the photo, there are two of us. We live and work together 24/7, studying and enjoying our grandchildren. Our passion is to know and understand what will happen after death. Is there a way to provide for and invest in that?
