147. The essential of the doctrine of the New Church which is called the New Jerusalem is this concerning the Lord; and he who wishes to be therein acknowledges it. For this Church is the very Christian Church, and no one is admitted there unless he who thinks of and believes in one God, thus the Lord alone. It ought to be known that each one is admitted into heaven in accordance with his confession of God. He is examined as to the quality of his thought and faith concerning God, for through that confession there is conjunction, and when there is conjunction there is enlightenment in every single thing. Everything of love and of faith depend thereon. Wherefore, those who deny God are in hell because [this brings about] separation. The first, and primary thing, therefore, is to know, to acknowledge, believe in, and love God. All other things depend on this.
