The resurrection of the dead comes also through a man

1 Cor 15:20-34
 But Christ has indeed been raised from the dead, the first fruits of those who have fallen asleep. For since death came through a man, the resurrection of the dead comes also through a man. For as in Adam all die, so in Christ all will be made alive. 
The last enemy to be destroyed is death. For he “has put everything under his feet.”
Do not be misled: “Bad company corrupts good character.” Come back to your senses as you ought, and stop sinning.
Christ's resurrection is the guarantee that his followers, too, will be raised from death. At the end, when Jesus comes to rule, death itself will be defeated.
Why?
Death came from a man, Adam, the resurrection of the dead comes also through a man. Jesus Christ.

Because we believe so do the right things there is conscious from the Lord , stop sinning
How?
I trust and believe that Jesus is resurrection from the death, so I devote myself to Him until that day.
