Jesus Christ taught us special righteous laws...it is no coincidence that those laws lead us to a deep and meaningful knowledge about all Creation...hence, by default, Jesus taught us what Almighty God already knew...that our human existence relies heavily on us grasping those complicated laws. We simply didn't have the intellect so Almighty God did the next best thing...he sent his only begotten son to live those laws and to show those who rather fancy repair, resurrection and everlasting life that it can only be achieved by following those righteous laws...ok.
The best advice that anyone can offer those who don't think this is true is...follow the accurate teaching of Jesus Christ and thereby make this terrible world a better place...and also be in with a shout when that final trumpet blows.
