The Fist man Adam disobeyed God's command, "In the day that you eat from it[the tree of life] you will surely die." As a result, Adam and his descendants became sinners and therefore could no longer have eternal life. But God sent His begotten Son Jesus to save mankind.
Jesus, who came to this world only performed good deeds; preached the gospel of heaven, healed the sick, and finally died on the cross to redeem us from our sins. Then, on the third day, He resurrected from the dead. From thence, anyone who accepts Jesus Christ receives the right to become God's child and gains eternal life and can enter heaven. God manifested this great love toward us.
