We came to this world with an empty brain, it is when we get to the world that we acquire knowledge to fill it.
Some we acquired by impartation, be it self-impartation or by an external force, some we pay for to acquire, some we acquire through thinking and meditation.
But you know that the best knowledge you can acquire is the knowledge from the WORD OF GOD.
With His WORD, we cannot stumble because it will light our path. (Psalms 119:105).
