How am I a party to the covenant of atonement?

Jesus prayed (Jn 17:21) that “they may be one in us as you are in me and I am in you.” (Easier to comprehend if *in* means *in union with*.) This is the original sense of at-one-ment. “We also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.” (Ro 5:11; KJV uses atonement) Here’s what happened: Adam and Eve’s sins (and mine) separated me from God and put me on a different path. So God put Adam and Eve (and all their descendants) out of Paradise to learn how to choose between good and evil. At first, we were at-one with God. And then not. Our sins have put us on a path different from God’s. “Give ear and come to me; listen, that you may live. I will make an everlasting covenant with you,” (Isa 55:3a,b). "This is the covenant I will make with the people of Israel after that time," declares the LORD. "I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.” (Jer 31:33) It's a given that atonement cannot be accomplished by my efforts alone; otherwise, Jesus would not have had to undergo His passion and death. But if atonement brings God and me together, isn’t it I, not God, who must change? What must be done to bring about atonement? A beautiful metaphor in Hebrews identifies Jesus as High Priest of His own death, recalling the holy Temple offerings to God. But the death of Jesus was not a suicide, and was *not demanded* by God. Our God is not like the pagan gods which delighted in human sacrifice; this is proved by the binding of Isaac. The death of Jesus was caused by *corrupt human powers of the time*. This is what God did: Jeremiah prophesied (31:31) that Yahweh would write a new covenant on His people’s hearts and forgive their iniquity and never call their sin to mind. God said to Isaiah,“Give ear and come to me; listen, that you may live. I will make an everlasting covenant with you.” (55:3) This new covenant would be our atonement - if only we listened to our hearts and let it happen. But we have free will; perhaps more exactly, we have *free choice*. God always lets us choose to *desire* this or that. Atonement is not done *to me* or *for me* without my involvement, but rather, is the result of the covenant relationship that I am offered. But distractions always pop up. But something can begin within us, which then allows us to make a choice: the death of Jesus could elicit compassion from even the hardest heart. It’s part of being human. If I don’t resist it, I would be drawn to feel compassion, not only for Jesus, but also for God the Father, who is suffering the torture and murder of His beloved Son. This compassion that suffers with Jesus could be a response to the covenant God offers. Paul went further: if we are … *baptized into his death* (Ro 6:3 NIV), *united with Him in a death like His … [then we will be] certainly also united with Him in a resurrection like His* (v5). This surely implies more than just sprinkling with water and words; it must mean being immersed into His agony, by a natural compassion that leads to a mystical union with Him. *Immersed into His death.* My compassion, love, turns toward my Father in Heaven as well as toward His Son Who died to get my attention… *to forgive me*. As I become immersed into the passion of Jesus, I realize that I am not the innocent, compassionate bystander, but at the heart of the matter, *I’m* guilty of the death of Jesus. His death tears me apart while His Holy Spirit wants to cry out in my heart, “Abba, Father.” After being brought before the throne of God, I hope to hear again, “Father, forgive him - he’s a friend of mine.” ***What other verses (or wisdom) from the Bible might support the idea of a continuing covenant, with my active involvement, rather than a one-time event, without my active participation, with regard to the atoning death of Jesus?***
