wannabe,
Every one who references Jesus has to use the Bible. That's where the Jesus story comes from. Jesus in turn references the OT but it is interesting that he discouraged his disciples from mimicking the judgmental retributions that everyone ascribes to his Father. There is no "eye-for-an-eye" with Jesus.
His disciples at Luke 9:54-56 (in many translations) has Jesus rebuking his disciples for wanting to call down fire from heaven to destroy a Samaritan village that is rude to them. Jesus instructs them:"Ye know not what manner of spirit ye are of. For the Son of man is come not to destroy men's lives but to save them."
The value of the OT may be that we can see that we need to follow Jesus in the Spirit as he directed us.It may even be that we don't really enjoy spiritual brotherhood by designating ourselves as "children of Abraham"( so to speak) But we may individually listen to God even as Abraham did listen, really listen to God. The work of Abraham was not knowing but really listening.
It is interesting to think that this Father of faith, Abraham, had so little doctrine to pass on, so little in the way of warning or teaching. But in the way of remembering the names of OT patriarchs, Abraham, Isaac and Jacob, etc. they are notable to me for their solitary wrestlings with God.
We are not adequate to judge each other or direct one another in these wrestlings. There is great value in discussing these scriptures, but when I thing of the horror we felt in hearing 2 Tim. 3:6 "always learning but never coming to an accurate knowledge of the truth..." it was a misplaced horror in that it was not becoming proficient at a packaged religion.
No.
If Jesus was right about bringing healing with his life, teaching and death then we must pay attention to this:
"Be compassionate as your Father is compassionate. Do not judge and you will not be judged yourselves; do not condemn, and you will not be condemned yourselves; grant pardon and you will be pardoned. Give and there will be gifts for you a full measure, pressed down, shaken together, and running over, will be poured into your lap; because the amount you measure out is the amount you will be given back." Luke 6:36-38
So don't worry, wannabe. You concern is best left to rest in Jesus' lap. Don't worry about missing the boat and just teach others what good things the Lord has done for you and the mercy he has shown to you. Is told that to Legion an that is all that I know to do myself.
May God give you peace and rest,
Maeve
