Let’s continue our analogy of planning to go to Paris. I have done my research and know where Paris is located. I know how much I need for the airplane ticket, hotels, tours and meals, but I do not have enough money to go. Now I need self control (temperance).
I need to save up the money to go. I need to spend less on going ti the movies, eating out, going on shopping sprees, and buying chocolate.
So it is with our walk with God. It is not enough to have faith, to be virtuous, to know right from wrong. We must discipline ourselves to act in the way we know is right (2 Peter 1:6).
