You are not following your own Reformed Theology now.
Grace is extended to only some, those that God has pre-selected.
In your dogma if you present it accurately it is....
Jane Smith is deliberately foreordained to commit sin.
Is hated by God
Is predestined to hell because God withholds His Grace, salvation is intentionally out of reach for her.
Is deliberately excluded from the atoning sacrifice of Jesus
Jane Smith will be judged by a god and sent to hell because he favored someone else over her
This is a god who essentially goes against his own commandments where believers are called to love those he hates?
Tell me do not see a problem here?
And do not forget....The same god who made little miss Smith for hell decided that one thief on the cross out of two got lucky even though both were murderous thieves being crucified by the ROMANS......
