One God, One Will (Exodus 3:14; 1 Corinthians 8:4-6 (LD 8 COD Head 5 Article 1)

The doctrine of the Trinity is a rather confusing doctrine.  In fact, it is a doctrine that we will not fully grasp or understand as creatures possibly even during glory. So, if this doctrine is so difficult can we really know our God?  What is good about such a confusing doctrine?  What does this doctrine have to do with our redemption?  In other words, if we cannot understand this doctrine then why talk about it?  What does such a doctrine have to do with the doctrines of grace?

God as Savior (Titus 1:1-4; LD 8)

The doctrine of the Trinity is one of the most confusing doctrines that we have in Christianity.  This is one of those doctrines that really distinguishes Christianity from all other religions.  So, we can see or understand the significance of this doctrine because it defines our God as being very distinct from all other gods.  However, if this doctrine is something that is so divisive how do we know that it is really in scripture?  Is this doctrine so essential for us understanding our Lord?
