We live in a messed-up world. No one would argue with that. The controversy arises over how the world got messed up in the first place. The Bible gives us a clear answer: “sin entered the world through one man and death through sin, and so death spread to all people because all sinned.” Adam messed everything up, and we've succeeded at keeping it in that condition.
Is there any hope for our world? The Bible provides another clear answer: “those who receive the abundance of grace and of the gift of righteousness [will] reign in life through the one, Jesus Christ!” Jesus will set everything right again.
For next time, read Romans 6:1-14.
