One of the grandest mysteries of G-d is his foreknowledge. Truth is knowledge of things they are, as they were and yet to come. G-d, possessing all truth, has the ability to know all things in advance. This being the case, we can trust him to give us only that which will be good for us in completing our life's mission successfully.

G-d never uses his love to hurt us. To do so would countermand his own law of judgement "do unto others as you would have them do unto you." So he will never let us down, never forsake us. His love is extended to all and he knows exactly how to reach each person.
