Secrets are not secrets, they are common sense. Why they seem like secrets remains a mystery.
“To you it has been given to know the secrets of the kingdom of God; but for others they are in parables, so that seeing they may not see, and hearing they may not understand. 11) Now the parable is this: The seed is the word of God. 12) The ones along the path are those who have heard; then the devil comes and takes away the word from their hearts, that they may not believe and be saved. 13) And the ones on the rock are those who, when they hear the word, receive it with joy; but these have no root, they believe for a while and in time of temptation fall away. 14) And as for what fell among the thorns, they are those who hear, but as they go on their way they are choked by the cares and riches and pleasures of life, and their fruit does not mature. 15) And as for that in the good soil, they are those who, hearing the word, hold it fast in an honest and good heart, and bring forth fruit with patience.”
