Gods love is conditional, we must keep his word or burn in hell fire forever. We are guilty from the begining of our lives but because God so loved us he sacrificed his own begotten son to torture and death so that we might not perish. We did not deserve that grace and Christ Jesus did not deserve to be tortured, so we continue to feel guilty becuase of the way God loves us. To be loved by God is to be burdened with guilt and fear.
