When God created the heavens and the earth, the plants, animals, and mankind He was pleased with what He had done, calling it "very good." He placed mankind (Adam & Eve) in the garden of Eden and told them to "be fruitful and multiply." They had nothing to fear, food for the taking, and everything they needed. In other words, it was the good life, a true eutopia. There was one condition from God, "Of every tree of the garden thou mayest freely eat: but of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die." Genesis 2:16-17 KJV
One day Eve was enticed by a serpent (Satan) to eat of the tree telling her it would make her as a god. She gave in to the temptation and Adam who was with her also did the same (Gensis 2:1-7). That is when sin entered the world. Their desire for personal satisfaction over that of God was their undoing and consequently ours (Romans 5:12). We have inherited hat same desire to be our own gods and think we no longer need God in our lives. Because of our sin we deserve death for the wages of sin is death (Romans 6:23).
God is perfect and just, and He cannot exist along with sin and demands justice. A justice that He commands can only come through a blood sacrifice (Leviticus 17:11). God in His love and mercy sent His only Son to be that perfect and final sacrifice on our behalf and then rise again proving that He had overcome death.
The good news is that Jesus invites all of us who believe and trust in Him to be risen to eternal life with Him in heaven as He said, "God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved." John 3:16-17 NKJV
And...
"Come to Me, all you who labor and are heavy laden, and I will give you rest. Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls. For My yoke is easy and My burden is light.” Matthew 11:28-30 NKJV
The good news is that we all can be saved if we humble ourselves, let go of our pride, and turn to Him, "For this is good and acceptable in the sight of God our Savior, who desires all men to be saved and to come to the knowledge of the truth." 1 Timothy 2:3-4 NKJV
