There is, for everyone, a crossroads when it comes to spiritual things, a basic decision to be made. Are you going to believe in the Lord and in spiritual reality? Or are you only going to believe what you can see, touch, feel and otherwise "know" from your own mind? The Writings say those who choose the latter course are closing themselves off from the truth, because by definition spiritual reality cannot be seen, touched, felt or otherwise "known" through purely human means. That's what it means to eat "of the tree of the knowledge of good and evil," and it leads to spiritual death – which is being cut off from the goodness and truth the Lord wishes to bestow on us.

The people of the Most Ancient Church were in a state of love to the Lord, and had been invited to gather all the wisdom and knowledge flowing from that love – the fruit of all the other trees. But they had to accept the Lord as the source, had to accept that He existed, had to accept that He was infinite and beyond their finite understanding. To think otherwise – to think that through their own minds they could explain the Lord – would be to put themselves above him, and lead them into evil.

It's worth noting that this was not a call for people to shut down their minds. The fruit of the other trees represents an incredible bounty of exploration, learning and wonderment. And we're not called on to shut down our minds today; the Lord gave us our intellectual faculties for a reason. To let the Lord in, though, we have to accept the unprove-able idea that He is love itself and reality itself, and see all other knowledge in that light.

769. Who keep the commandments of God, signifies with those who live the life of faith, which is charity. This is evident from the signification of "keeping the commandments of God," as being to live according to the commandments in the Word; and as that life is a life of faith, and a life of faith is charity, therefore "keeping the commandments of God" signifies to live the life of faith, which is charity. The life of faith is charity towards the neighbor, because faith means faith in the Word, thus faith in the truth that is in the Word and from the Word, and charity means the love of good and truth, spiritual, moral, and civil; and as that which man loves he also wills, and what he wills he does, therefore "keeping the commandments of God" signifies to live the life of faith, which is charity.

[2] From this it can be seen that all those who separate faith from charity know not what faith is or what charity is, for they have no other idea of faith than as being everything of the memory that is believed because they have heard it from learned men; and yet such faith is historical faith, for they do not see whether a thing is so, except because someone else has said it; and what is seen from another can be confirmed both by the sense of the letter of the Word misunderstood and by reasonings from appearances and knowledges [scientifica], although it may be a falsity directly opposed to the truth.

When this is confirmed it becomes a persuasive faith; but neither this faith nor historical faith is a spiritual faith, thus not a saving faith, for such faith has as yet no life from the Lord in it. That a man may receive that life he must live according to the Lord's commandments in the Word, for living according to these commandments is the same as living from the Lord, because the Lord is the Word and is in the Word. Such a life is the life of faith, which is charity; and then its affection becomes charity, and thought from that affection becomes faith; for all man's thought derives its life wholly from affection, since no one can think without affection; therefore when a man's affection becomes spiritual his thought also becomes spiritual; consequently such as a man's charity is such is his faith. From this it can be seen that charity and faith, like affection and thought, or what is the same, like will and understanding, act as one, for affection is of the will and thought is of the understanding, consequently they act as one as goods and truths do. Thence it is clear that to live according to the commandments of the Lord from the Word, or "to keep the commandments of God," means to live the life of faith, which is charity.
