When Adam and Eve ate of the tree of the knowledge of good and evil the Lord said that they would die. The Bible says that the sin brings death. Man earned death when he sinned.
When Adam and Eve sinned in the garden then they brought a curse on themselves. The curse was the consequence of their disobedience and if they will not fight it but submit to the new boundary, which the curse brought, then it would keep them from sinning some more which would bring even more curses. Sin brings a curse. To be set free from the curse someone else had to take the curse that Adam and Eve brought on themselves by their own sin.
When Adam and Eve lived in the garden before they sinned they heard God’s voice. It was the voice of comfort and the voice of a loving God who cared for them. They exchanged the voice of a loving God to hear the voices of their own accusations. When the love is gone in relationships then blame and accusations come in. Where there is sin there will also be blame and accusations.
When Adam and Eve were in the garden of Eden before they sinned they did not need any rules other than the one that the Lord had given to them. They loved God and they loved each other. Their love was perfect for God and for each other because their hearts were pure. They had never known any evil.
Love brings great joy to the one who loves and to the one who is loved. Joy is different than happiness. Happiness comes from what is happening but joy comes from something else. Joy comes from being in the presence of God.
