Old covenant was types and shadows but the reality is JESUS CHRIST.  (Colossians 2:17) And then Paul and the disciples expanded this Amazing Grace to understand it better.  We are now a royal priesthood, a chosen people, a holy nation. GODS special prized possession  1 Peter 2:9  The disciples went from servants to friends to sons. And that is where we are now - sons and daughters having a better covenant (Hebrews 8:6) and I believe we are learning and writing further bible chapters (our lives) elaborating on HIS Grace as the SPIRIT teaches more and more about SPIRITUAL things.

Additional thoughts>>> if GOD was blood thirsty wanting death/destruction - can't wait to smash people when they step out of line. Then you would have no problem believing this angry/madman (GOD) is quick to throw in hell everyone that doesn't say a prayer right or can't quite forgive someone or can't even forgive him/herself.   But then why does HE say that HE loves the world so much? (John 3:16/17) And not only love it but will not condemn it? Why does HE say that its possible for mother to (maybe) perhaps abandon a child but GOD could not ever (its impossible) for GOD to abandon you!

Isaiah 49:15 "“Can a mother forget the baby at her breast and have no compassion on the child she has borne? Though she may forget, I will not forget you!"

its about love, GOD is love - anything else its either HIS loving discipline Hebrews 12:6 but NOT punishment, NOT hell, NOT torment, NOT "i will getcha" .   

I was counselling /encouraging one churchy lady years ago, she came into our Healing rooms drop in centre in Toronto for prayer.  She told me she was going through some very tough times. There was sickness and wayward son and a come & go husband. She told me it was "God" who was punishing her, that God (in the problem) was taking her behind the shed and giving her a whooping ..letting her have it.  That this "God" has to and wants to do this because she deserved it and this God wouldn't/shouldn't be messed with.  She was cursed (she thought and her thoughts became real and she created this world) but she was convinced that there was sin in her life and wrong going on, so that this God HAD TO do it. 

 I asked how did that make her feel? She said well its a very scary place and very dark. She can't sleep well and she is always prepared for the other shoe to fall off and she would get another deserved ass kicking by this God.

I said "Your God sounds more like my devil!"

She was shocked - I mean she just stared at me and thought this God would now strike me dead just for talking sacrilegious foolishness.

She stormed out, shaking her head not really able to comprehend and yet not wanting for me to give another word  - and certainly didn't want me praying for her.

I think the SPIRIT made HIS point to her, always revealing the true nature of GOD to us. 

Remember the fruit of the SPIRIT we are supposed to grow and have?  "the fruit of the SPIRIT is love, joy, peace, patience, kindness, generosity, faithfulness, gentleness and self-control" this is the SPRIITS fruit - this is what GOD is like and by partaking the Devine nature (by believing what HE says) we start producing these things and living this (abundant) life.
