"Gave" Whats written in the bible. I just explained as die for us. 

After Jesus' death, his disciples were hiding for fear of suffering the same fate as their master. They were convinced that Jesus' life had failed and everything was lost. Nevertheless, we see them coming a few weeks later, publicly proclaiming that Jesus has risen and lives.

As long as we live on this world will we be sinners because the devil is here. The only person who have lived in world and has never sinned is Jesus christ. Therefor we are all sinners and no one can be 100% sin fri, but god love us so much so he want to give us the eternal life as a gift even that we don't deserve it, so that we only have to believe in him/jesus and we are saved.

Because of Jesus' death, we have again become "the children of light". "Children of Light" is actually an expression New Testament uses those who believe in Jesus (eg Ephesians 5,8). Many mistakenly believe that Jesus in the day of judgment should stand like a whimsical judge and say "pigeons, do not you". 

As if Jesus wanted to judge someone. But Jesus does not want to judge anyone. On the contrary, he wants everyone to be saved. It is as Jesus says in the Gospel of John in the known place: "For thus God loved the world that he gave his only begotten Son, that every one who believes in him should not perish but have eternal life. 

For God did not send his Son of the world to judge the world, but that the world should be saved by him. He who believes in him is not judged: he who does not believe is already convicted because he has not believed in the only-begotten Son's name. the judgment that the light has come to the world and the people loved the darkness rather than the light 

Ephesians 2:8: For it is by grace you have been saved, through faith and this is not from work, it is the gift of God.
