Actually, to say God "speaks" to us takes us only so far in our understanding. A deeper word is communion. A husband and wife may sit together and say nothing, but just enjoy each other's presence. It is more so with God. We enjoy a silence in His presence, saying nothing. It is enough to be with God. That is fullness. Is there communication? As we wait in God's presence, the Holy Spirit brings an awareness of God to our spirit that has no equal in natural thinking. Our response is one of worship and adoration. The future revelation of Jesus Christ in fullness is foretold in the book of Revelation, and all present revelation of Jesus Christ to our hearts is a foretaste of that glorious day when we shall no longer see "in a mirror dimly," but face to face (I Cor. 13:12).
The Holy Spirit is spoken of as the guarantee, or down payment, until the redemption of the purchased possession (Eph. 1:14). Consider the response of the elders, as the Lamb was revealed. They cast their crowns before the throne, and fell down and worshiped the Lord (Rev. 4:11). Jesus is the same, yesterday, today, and forever--the same today as He will be on that day (Heb. 13:8). For us to see Him as He is requires that the Holy Spirit reveal it to our hearts.
This revealing is given to those who draw away to a quiet place with God, and have an ear to hear God. Jesus must apply the "eye salve" to the eyes of our hearts (Rev. 3:18) so that we may behold Him. When we do see Him in His glory, we are likely to hear these words from God: "This is My beloved Son, in whom I am well pleased. Hear Him." (Matt. 17:5)
"See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven" (Heb. 12:25).
"Therefore we must give the more earnest heed to the things we have heard, lest we drift away. For if the word spoken through angels proved steadfast, and every transgression and disobedience received a just reward, how shall we escape if we neglect so great a salvation?" (Heb. 2:1-3)
Brethren, let us hear God.
