Victory is a Gift and NOT a reward.
What is a Gift?
It is something which is Freely Given to you.
That which you earn through work is a reward.
A Gift, on the other hand, ask for no effort on your part.
It is that which is Given Gratuitously with no requirement placed upon the receiver, whereas a reward demands that someone work for it.
Victory is something which God has Prepared to Give to us.
Our Victory is Obtained Freely, not attained through self-effort.
