We should know what our convictions are, and stand for them. Upon one's own philosophy, conscious or unconscious, depends one's ultimate interpretation of the facts. Therefore it is wise to be as clear as possible about one's subjective principles. As the man is, so will be his ultimate truth.
'We were created for eternal life by our Creator, we are called to it by the word of God, and we are renewed by holy Baptism. And Christ the Son of God came into the world for this, that He should call us and take us there, and He is the one thing needful. For this reason your very first endeavor and care should be to receive it. Without it everything is as nothing, though you have the whole world under you.' -- St. Tikhon of Zadonsk
