No Salvation in Opinion

There is no salvation in correct opinions, neither is there damnation in wrong opinions. Suppose your theories right, suppose they contain all that is to be believed. Those theories are not what makes you a Christian, if a Christian you indeed are. On the contrary, in many cases they are just what keeps you from being a Christian. For when you say that, to be saved, one must hold to this or that notion, you are putting your trust in some idea about God, rather than in the living God and His will.
It is one thing to believe in a god: it is quite another to believe in God! One of four gates stands open to us: to deny the existence of God; to acknowledge His existence but say He is not good; to say, "I wish there was a God," and be miserable because there is none; or to say, "There is a God, and He must be perfect in goodness or He could not be," and thus give ourselves to Him heart and soul. - George MacDonald
