Jesus has conquered death, hell and the grave!
John 5:24 Jesus said, "He that hears my word, and believes on Him that sent Me, has everlasting life, and shall not be condemned, but is passed from death unto life".
John 14:6 Jesus said, "I am the Way, the Truth, and the Life.  No one comes to the Father except through Me".
1 Corinthians 15:35 But someone will say,  "How are the dead raised up?  And with what body do they come?"
1 Thessalonians 4:16-18 For the Lord Himself shall descend from Heaven with a shout, with the voice of an archangel, and with the trumpet of God.  And the dead in Christ shall rise first.  Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air.  And thus we shall always be with the Lord.  Therefor comfort one another with these words.
1 John 3:2 Beloved, now we are the children of God, and it has not been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. 
Now we can say, "O death, where is your sting?"
                            "O grave, where is your victory?"
