The view that God’s exercise of his foreknowledge is infinite and that he does foreordain the course and destiny of all individuals is known as predestinarianism. Its advocates reason that God’s divinity and perfection require that he be omniscient (all-knowing), not only respecting the past and present but also regarding the future. According to this concept, for him not to foreknow all matters in their minutest detail would evidence imperfection.

The argument that God’s not foreknowing all future events and circumstances in full detail would evidence imperfection on his part is, in reality, an arbitrary view of perfection. Perfection, correctly defined, does not demand such an absolute, all-embracing extension, inasmuch as the perfection of anything actually depends upon its measuring up completely to the standards of excellence set by one qualified to judge its merits. (See PERFECTION.) Ultimately, God’s own will and good pleasure, not human opinions or concepts, are the deciding factors as to whether anything is perfect.​—De 32:4; 2Sa 22:31; Isa 46:10.

To illustrate this, God’s almightiness is undeniably perfect and is infinite in capacity. (1Ch 29:11, 12; Job 36:22; 37:23) Yet his perfection in strength does not require him to use his power to the full extent of his omnipotence in any or in all cases. Clearly he has not done so; if he had, not merely certain ancient cities and some nations would have been destroyed, but the earth and all in it would have been obliterated long ago by God’s executions of judgment, accompanied by mighty expressions of disapproval and wrath, as at the Flood and on other occasions. (Ge 6:5-8; 19:23-25, 29; compare Ex 9:13-16; Jer 30:23, 24.) God’s exercise of his might is therefore not simply an unleashing of limitless power but is constantly governed by his purpose and, where merited, tempered by his mercy.​—Ne 9:31; Ps 78:38, 39; Jer 30:11; La 3:22; Eze 20:17.

Similarly, if, in certain respects, God chooses to exercise his infinite ability of foreknowledge in a selective way and to the degree that pleases him, then assuredly no human or angel can rightly say: “What are you doing?” (Job 9:12; Isa 45:9; Da 4:35) It is therefore not a question of ability, what God can foresee, foreknow, and foreordain, for “with God all things are possible.” (Mt 19:26) The question is what God sees fit to foresee, foreknow, and foreordain, for “everything that he delighted to do he has done.”​—Ps 115:3.
