just listened to a message from the 2005 Children Desiring God Conference. one thing among many that really struck me was the following...
God chooses to reveal Himself in mighty ways only a few times in history. Events that come to mind are the Flood, Sodom/Gomorrah, freeing Israel from Egypt (10 plagues including Passover, crossing the Red Sea and Jordan River on dry land, through the wilderness), Elijah's showdown with the prophets of Baal, and most notably, Jesus Christ and His life and ministry.
Why does God exhibit His mighty, glorious powers so far and few between? Part of the reason is God's desire for the witnesses of these events to tell of His mighty deeds to the generations to come, even the ones that have yet to be born. People have been known to be story tellers from ancient times. The greatest stories we have to tell are about God and His mighty deeds. For the witnesses of these great acts of God, they (and not God Himself) are the ones responsible for declaring God's glory to the next generation. (Of course, God's Spirit must guide the correct transmission of it so it doesn't get distorted for our own glory.)
The majority of people throughout history will never have personally witnessed any miraculous deed from God's mighty hand. But that doesn't mean they aren't true. Part of our responsibility as believers is to continue the transmission of the glory of God to every generation, in order that this next generation will tell it to their next generation. All the saints that have come before us have left a testimony of the greatness of God to us today. In particular, the saints that wrote the words of Scripture have obviously contributed the most in this endeavor. So though God may no longer part seas and rivers or bring down plagues upon nations, because of the transmission of the God's great deeds by the saints of old, written for us in Scripture by the power of the Holy Spirit dwelling in them, we are able to know and develop a passion for God's glory.
We see this pattern throughout Scripture. God tells His people often to remember Him and His mighty deeds, which our fathers have told us (or are supposed to tell us); consider Deut 6. God, being ever-consistent, has not changed this pattern. It is true for us today as much as it was for Israel during the Exodus. But on this side of the cross, we have an even greater story to tell than the Exodus. We know of (and must develop a passion for) the works of Christ, particularly on Calvary on the cross. Our responsibility is to spread the glory of God in Christ Jesus to the next generations, first of all in our own families, then in our local churches, to the ends of the world (through the local church), which, by God's grace will also impact the future generations to come, to the ones we'll never meet on this side of heaven. Saints of old have done their job so we know of the greatness of God. We look to the biblical saints, to the early church fathers, the Reformers, and the Puritans. Let's continue their work, as commissioned by God Himself, by the power of His Spirit.
