Logos Word verses Rhema Word

Jesus is the "Logos", the "Word," the personal manisfestation of God in the flesh (Matt 1:23). Rhema denotes "that which is spoken. The significance however of rhema as distinct from logos is that "to take the sword of the Spirit, which is the word of God" Eph. 6:17, here the reference is not to the whole Bible as such, but to the individual scripture which the Spirit brings to our rememberance for use in time of need, a prerequisite being the regular storing of the mind with Scripture.
