According to the Gospels, Jesus promised that by believing in him and his teachings, we would have eternal life. When his friend Lazarus died and his sister said to Jesus, "I know that whatever you ask of God, God will give it to you." Jesus answered "Your brother shall rise again." When Martha, the sister of Lazarus was confused about this, Jesus said "I am the resurrection and the life. He who believes in me shall not die, but have everlasting life." Then Jesus said "Lazarus, come out!" Thus, Lazarus was raised from the dead. What Jesus meant in his words to Martha was that even when our bodies die, our spirits live on in the Afterlife. When Jesus was dying on the cross, the thief on the cross beside him said "Lord, remember me when you come into your kingdom." Jesus replied "I promise you that today you will be with me in Paradise." Thus, Jesus promised us that belief in him as the Savior who died for all our sins would give us everlasting life in Heaven. The last words of Jesus before he died were "It is accomplished." By this he meant that he had redeemed us all from our sins by allowing his own life to be taken as a sacrifice to God. This is similar to what Jesus told his disciples at the Last Supper; "In my Father's house are many rooms. I am going there to prepare a place for you." Now you see the many promises that Jesus made and how we can obtain eternal life.
Jesus promised that they who would call upon His name would be saved, that if we picked up the cross and denied ourselves that we would have an inheritance of Eternal proportions in Heaven. He promised that through His death, resurrection and ascension that His Holy Spirit would come, to lead and guide us into all Truth, would be a Comforter/Strengthener, would convict the world of sin. He promised the Victory over Death and Sin through His Spirit and the Holy bloodshed. He promised that all who suffered at His name would be greatly rewarded, that Satan would be under His feet along with Death and that sin would be eradicated. He promised a reward to EVERYONE, the evil and the good, the believer and the unbeliever, the one who worships Him and the one that doesn't. He means every one.
Two different questions, and once one understands that God does not exist and one can *not* have eternal life, then Jesus's empty promises are revealed as meaningless.
