Clement of Alexandria

But there is that species of knowledge which is characteristic of the herald, and that which is, as it were, characteristic of a messenger, and it is serviceable in whatever way it operates, both by the hand and tongue. "For he that soweth to the Spirit, shall of the Spirit reap life everlasting. And let us not be weary in well-doing." On him who by Divine Providence meets in with it, it confers the very highest advantages,-the beginning of faith, readiness for adopting a right mode of life, the impulse towards the truth, a movement of inquiry, a trace of knowledge; in a word, it gives the means of salvation. And those who have been rightly reared in the words of truth, and received provision for eternal life, wing their way to heaven. Most admirably, therefore, the apostle says, "In everything approving ourselves as the servants of God; as poor, and yet making many rich; as having nothing, yet possessing all things. Our mouth is opened to you."
