Isaac means to laugh. Ishmael means God listens. Perhaps you have to be willing to sacrifice your need for entertainment in order to have a serious relationship with God?
Doesn't anybody look beyond the surface of these things anymore? Especially ancient documents written during a time when poetry and metaphor was an art form. When the king could kill you for speaking the truth, ciphers and codes were developed.
Ananta, this is from the Metaphysical Bible Dictionary, by Charles Fillmore. (And he is a fully Western 'christian' of the Truth mold)
Isaac, I'-saac (Heb.)--He (God) laughs; He will laugh; laughter; joy; singing; leaping.
Son of Abraham and Sarah (Gen. 18:9-15; 21:1-7).
Metaphysical. Divine sonship. Isaac, meaning laughter, signifies the joy of the new birth and the
new life in Christ, which is the spiritual consciousness of relationship to God the Father. Man rejoices
greatly in his privilege of expressing as the son of God.
According to the text, Isaac was born after Sarah was past the age for bringing forth. Besides,
she was barren, so that there was no possibility of his conception under the natural course of things. So
we, when born of Spirit, are born, "not... of the will of the flesh, nor of the will of man, but of God." The
natural man has no power to bring forth "the new man" in Christ Jesus. So Hagar's son could not be the
chosen seed and heir. The new man is a "new creature," begotten by the divine seed, the Word. An
entirely new state of consciousness is formed, fulfilling the admonition, let "Christ be formed in you."
When Isaac was weaned, Ishmael, Hagar's son, mocked him. This is the experience of every one
in the new birth. The thoughts that are the fruit of the "mind of the flesh" rise up within and mock the
new man. Here the overcomer has a work to do. Hagar, the bondmaid and her son must be cast out.
Abraham grieves at this. So we sometimes grieve over giving up the fruits that we have brought forth in
the natural-man consciousness.
Isaac was not noted for his achievements; he represents the serenity, peace, and joy that man has
when he accepts spiritual things as real, and lives "as seeing him who is invisible."
At one time in my life I was a frequent user of this book and I also found I really liked Fillmore and his message. But I also found it was like my favorite chocolate--very sweet and easy to consume; but it has no lasting nutrition.
