Jesus died for the sins of the world

John 3:16-18
16 "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but to save the world through him.  

 

Hebrews 9:28
...so Christ was sacrificed once to take away the sins of many people; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.  

 

Luke 24:1-8
On the first day of the week, very early in the morning, the women took the spices they had prepared and went to the tomb.  They found the stone rolled away from the tomb,  but when they entered, they did not find the body of the Lord Jesus.  While they were wondering about this, suddenly two men in clothes that gleamed like lightning stood beside them.   In their fright the women bowed down with their faces to the ground, but the men said to them, "Why do you look for the living among the dead?  He is not here; he has risen! Remember how he told you, while he was still with you in Galilee:  'The Son of Man must be delivered into the hands of sinful men, be crucified and on the third day be raised again.'" Then they remembered his words.  

 

1 Corinthians 15:3-8
For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Peter, and then to the Twelve.  After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.  Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born.  

 

1 Thessalonians 4:13-17
Brothers, we do not want you to be ignorant about those who fall asleep, or to grieve like the rest of men, who have no hope.  We believe that Jesus died and rose again and so we believe that God will bring with Jesus those who have fallen asleep in him.  According to the Lord's own word, we tell you that we who are still alive, who are left till the coming of the Lord, will certainly not precede those who have fallen asleep.  For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first.   After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.
