St. John refutes predestination and such

But perhaps someone will say, If all that the Father gives, and whomever He shall draw comes to You, if none can come to You except it be given from above, then those to whom the Father does not give are free from any blame or charges. These are mere words and pretences. For we require our own deliberate choice as well, because whether we will be taught is a matter of choice, and also whether we will believe. And here, by saying ‘which the Father gives Me’, He declares nothing else than that ‘believing in Me is no ordinary thing, nor one that comes of human reasonings, but needs a revelation from above, and a well-ordered soul to receive that revelation.’
St. John Chrysostom
