When Owen was defending his theology against Arminians and Papists and Pelagians, as he said he was in The Death of Death in the Death of Christ he is rough in his treatment of opponents and rigid in his logic because the stakes were high. But look at his preaching:
"Generally, this is taken for granted by all, that Christ is able to save us if he will; yea, who shall question his ability to save us, though we live in sin and unbelief? And many expect that he will do so, because they believe he can if he will. But indeed Christ has no such power, no such ability: he cannot save unbelieving, impenitent sinners; for this cannot be done without denying himself, acting contrary to his word, and destroying his own glory. Let none please themselves with such vain imaginations. Christ is able to save all them, who come to God by him. Whilst you live in sin and unbelief, Christ himself cannot save you...." location 10338 in the Kindle (Meditations and Discourses Concerning the Glory of Christ , Chapter 1)
I didn't keep quoting for length but if you keep reading he goes on in a beautiful way to assure us of "his power to save those that shall comply with his call is sovereign, uncontrollable, almighty, that nothing can stand in the way of. All things in heaven and earth are committed unto him; - all power is his; and he will use it unto this end,namely, the assured salvation of All that come to him."
