We must pray constantly for His enabling grace to say no to temptation, of choosing to take all practical steps to avoid known areas of temptation and flee from those that surprise us.
There is no point in praying for victory over temptation if we are not willing to make a commitment to say no to it.
The very first temptation in the history of mankind was the temptation to be discontent...that is exactly what discontent(ment ) is - a questioning of the goodness of God.
