Answer:

For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. (EPHESIANS 2:8-9).

JOB 42:2, ROMANS 11:36, ACTS 4:12

First of all, let’s take a look at the word “chance.” Chance means that something just happened; that it wasn’t planned. Nothing happens by “chance” because God knows everything. He doesn’t give us a second chance. He gives us a free gift—forgiveness through Jesus! 

When Adam and Eve sinned the whole creation fell—it was no longer perfect! Nothing humans could do could undo that. Adam and Eve were sent out of the Garden. But they continued to live on earth, have children, and teach their children and grandchildren all about God and His mercy. I believe that when God killed that very first animal and gave Adam and Eve clothes to wear, He was sharing a picture of the gospel, the message of salvation with them. He was helping them to understand that it would take a perfect sacrifice to take away the sins of all people and that perfect sacrifice would be God Himself—Jesus Christ. Everyone who believes in Jesus Christ as Lord and Savior will receive the free gift of eternal life in heaven.

Adam and Eve were dead in their sins and so are we. God gave us something far better than a “second chance.” What we do get is a free gift if we will receive it by believing and trusting in Jesus Christ.
