There is nothing wrong with violence in itself. In any particular case, whether violence is good or bad depends on how it is used and the purpose for which it is used.
Whenever God begins something, we have the assurance that He will finish it. Nothing will stand in the way of Him accomplishing His purpose in this world and in our lives. What God starts, He finishes, and nobody can hinder Him. Sure, delays will happen. Just remember, God is in charge of the delays as well as the progress.
There are no accidents, all things have a deep and calculated purpose; sometimes the methods employed by Providence seem strange and incongruous, but we have only to be patient and wait for the result: then we recognize that no others would have answered the purpose, and we are rebuked and humbled.
There is no good reason why we should fear the future, but there is every reason why we should face it seriously, neither hiding from ourselves the gravity of the problems before us nor fearing to approach these problems with the unbending, unflinching purpose to solve them aright.
And let there be no purpose in friendship save the deepening of the spirit. For love that seeks aught but the disclosure of its own mystery is not love but a net cast forth: and only the unprofitable is caught.
It is worthwhile for one to make an effort to achieve happiness. Just as the purpose of a plant is to grow, so it is that the main purpose of every human being is to survive and to grow until death.
