Wait!if one would actually look, they would see it is not very difficult
we are dead BECAUSE OF SIN - "the wage of sin is death"
which means, we can not be made alive until the sin issue is resolved.
The payment and forgiveness of sin, or answer to the sin problem is redemption. which leads to justification (A judicial term which means declaired righteous or innocent)
so justification MUST precede regeneration. Otherwise, you have a person who is dead because of sin, made alive IN SIN.
Here it sounds like you are saying the entire human world is already justified because Jesus paid the substitutionary price for all. If that is true, then all humanity is declared righteous. This means no one need respond to the gospel message since all humanity is justified.
Do you realize you are teaching universalism?
