The soul of man will live somewhere in eternity, either in a place of life or of death (Matthew 25:46). God has been clear in his word that his desire is for all men to be saved (1 Timothy 2:3-4).
However, he also has made it clear that there is a place that was prepared by the devil (Matthew 25:41), and those who refuse his offer of life will spend eternity there.
When Jesus stated that he had come so his sheep could have abundant life (John 10:10), he was offering something that only God can give. The idea is of continued blessing of life for every faithful soul.
Then, God gives man a choice to make. If they choose to take advantage of the “abundant life” offered by Christ, they can have heaven as their eternal home. But if they choose to ignore the offer of God, they will be lost and spend eternity in Hell.
People of the world only see the here and now, not looking to the future. Some do not even believe in God, or that they have a soul. They scoff at those who follow God (1 Corinthians 1:18; 2 Peter 3:3-5).
The Christian knows there is an eternity and is able to look beyond the physical realm to the glories of heaven. The Christian desires eternal life and realizes that laboring for the Lord is rewarding — not only now, but in eternity (Matthew 6:19-20).
Taking advantage of the “abundant life” requires adherence to God’s word. John recorded the Lord’s warnings against the “thief,” or false teacher, who has no regard for the “flock” but is out only for his own selfish ways. Those who follow false ways fail to understand the need to stay with the “book.”
Jesus said, “Not everyone that saith unto me, ‘Lord, Lord,’ shall enter into the kingdom of heaven, but he that doeth the will of my father, which is in heaven. Many will say to me in that day, ‘Lord, Lord, have we not prophesied in thy name? And in thy name have cast out devils? And in thy name done many wonderful works?’ And then will I profess unto them, ‘I never knew you. Depart from me, ye that work iniquity’” (Matthew 7:21-23). The way of the false teacher leads to death (John 10:10), but the way of Christ leads to life.  
Every person must search the Scriptures (John 5:39) in order to seek out God’s will, and then must obey the commands given (James 1:23). God wants man to be saved, but man must be willing to follow God.
