If so, not a very good stand-in imo.

"For God did not send his Son into the world to condemn the world, but to save the world through him.". John 3:17

Christ didn't come to reward the people already doing good, and punish those doing evil.

Rather, "[...]for all have sinned and fall short of the glory of God, [...]"

People are not justified by being "good enough" by themselves, but rather, are "[...]justified by his grace as a gift, through the redemption that is in Christ Jesus, [...]".

Your description of "You're punished for evil and rewarded for nice and he's watching you all the time?" is, I think, a very misleading and simplistic idea of Christ.
