God so loved the world that he gave (sent) his only begotten son so that all who believe in him should not perish but have everlasting life
God promised to send the Messiah to repair the gap between God and mankind.
God was not a sinner and forgave every one
Breaking a promise with God can have spiritual consequences depending on one's belief system. It may result in feelings of guilt, remorse, and a strained relationship with God. Some religious traditions teach that honest repentance and seeking forgiveness can help mend the relationship and restore spiritual well-being.
God's covenant with Adam was a promise of protection and provision in exchange for obedience. This covenant established a close relationship between humanity and divinity, with humans being given dominion over the earth but also being held accountable for their actions. The covenant emphasized the importance of following God's commands and living in harmony with His will.
Obedience was crucial to their relationship. The relationship was damaged when they disobeyed.

Before the Fall, Adam and Eve's relationship with God was characterized by direct communion and obedience, reflecting the essence of the first covenant. God provided them with the Garden of Eden, granting them freedom to enjoy its blessings under the condition of not eating from the Tree of Knowledge. This covenant was based on trust and a promise of life, with their obedience ensuring a harmonious existence with God. Their intimate relationship exemplified the ideal of covenant love, where divine provision and human response were perfectly aligned.
God promised Adam and Eve that they could enjoy the abundant resources of the Garden of Eden and live in harmony with Him and creation. However, He also instructed them not to eat from the Tree of the Knowledge of Good and Evil, warning them that doing so would lead to death. This promise included the potential for eternal life and a close relationship with God, contingent upon their obedience to His command.

If you believe the story of Adam and Eve to be a myth then it has no relevance at all. But if you believe the story to be true then it has great relevance. Because the story tells how man's relationship with God, the creator and sustainer of life, was broken when Adam and Eve disobeyed God. Also everybody born since Adam and Eve is born without a relationship with God.
After the fall? We are not told if they did or did not. But we can assume they did, their children did and presumably Adam and Eve instructed their children how to maintain their relationship with God.
God still loved them. God kicked them out of the "garden" not His life. Adam and Eve's disobedience came as no surprise to God. God instructed Adam and Eve how they could maintain their relationship with Him - through a blood sacrifice.
