To make no decision is always to make a decision against God — Martyn Lloyd-Jones

"There are only two ultimate possibilities in life. We are, all of us, either for God or else we are against Him, and nothing else matters. The color of your skin does not matter at all; you may be very clever, you may be very learned, or you may be ignorant and illiterate—it does not matter. The one question is: Are you one of God’s people, or are you one of the people who are against Him?

There is no other possibility. There is no such thing as neutrality in the realm of the spirit.

To make no decision is always to make a decision against God, for we are all by nature against Him.

“The carnal [natural] mind is enmity against God: for it is not subject to the law of God, neither indeed can be” (Rom. 8:7). We are all born God-haters; we are all against God. Some people, I know, say, “I’ve always believed in God.” But that means that they have never believed in Him. What they have believed in is some figment of their own imagination. If you confront such people with the God of the Bible, they will soon begin to show their hatred of Him. They have a God whom they can manipulate and handle, a God made after their own image and likeness, and they hate the living God who is revealed in the Bible.

So there is no such thing as neutrality. I repeat that we are either for God or we are against Him. There is no no-man’s-land in this matter. We all of us are inevitably in one of two camps. Our Lord Himself said it: “He that is not with me is against me” (Matt. 12:30)."
