The giver must be willing to give; the receiver must have knowledge that the thing is offered and must be willing to accept.

There must be two parties, the giver and the receiver; and there must be knowledge on the part of both.
For this reason we read: "This is good and acceptable before God, our Savior, who desires all men to be saved, and to come to an accurate knowledge of the truth".

(1 Timothy 2:3,4, _Diaglott_) The salvation here mentioned is effected by the great ransom-price which constitutes the price of deliverance.

Then all must come to a knowledge of this fact and either accept it or reject it, just as one who is offered a gift must either receive or reject.

Hence the Apostle writes: "Therefore as by the offense of one judgment came upon all men to condemnation; even so by the righteousness of one the free gift came upon all men unto justification of life".
