If we believe not, yet he abides faithful: he cannot deny himself.
All Commentaries on 2 Timothy 2:13 Go To 2 Timothy 2
Augustine of Hippo
AD 430
God is allpowerful, and, since he is allpowerful, he cannot die, he cannot be deceived, he cannot lie, and, as the apostle says, “he cannot disown himself.” Very much he cannot do, yet he is allpowerful. It is because he cannot do these things for the very reason that he is allpowerful. If he could die, he would not be allpowerful. If he could lie, if he could be deceived, if he could deceive, if it were possible for him to do an injustice, he would not be omnipotent. If it were in him to do any of this, such acts would not be worthy of the Almighty. Absolutely omnipotent, our Father cannot sin.
