So is a covenant with God everlasting, especially when God is the one telling the Jews it is everlasting? Therefore, Jews should be following the Laws God gave them? No, Baha'i teach that new "social" laws are put in place with each new messenger and the old laws are no longer applicable. So I'm still wondering what were the new "social" laws that Jesus brought with his new covenant?
God's overriding Covenant is that we will not be left without guidance.
Example - Genesis 17:7 "I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you.... "
Each Messenger fulfils that Covenant and also sets the requirements of the dispensation up to God's new Messenger. This lesser covernent, giving the laws is changeable and we can read in the Holy Books how each Messenger brings specific guidance and laws.
If we are obedient to the Overriding Covenant, then the example passages I have posted below unfold with each Messenger, we listen and act upon what God has revealed through them and submit to God in the age we live.
Psalm 119:97-101 Oh, how I love Your law! It is my meditation all the day. You, through Your commandments, make me wiser than my enemies; for they are ever with me. I have more understanding than all my teachers, for Your testimonies are my meditation. I understand more than the ancients, because I keep Your precepts. I have restrained my feet from every evil way, that I may keep Your word.
Psalm 119:104 Through Your precepts I get understanding; therefore I hate every false way.
Psalm 119:111-113 Your testimonies I have taken as a heritage forever [this word “forever” is extremely important], for they are the rejoicing of my heart. I have inclined my heart to perform Your statutes forever, to the very end. I hate the double-minded, but I love Your law.
Psalm 119:115 Depart from me, you evildoers, for I will keep the commandments of my God!
Psalm 119:126 It is time for You to act, O Lord, for they have regarded Your law as void.
If I reject God's overriding Covenant and reject a Messenger, then I have broken the Law and it would not matter if I practice all laws past, I have rejected what it was to be Loyal to the Covenant of God.
