A helpful quote about devotional Bible reading:
Because the Scripture is a corpus, a living whole, the so-called lectio continua or consecutive reading must be adopted for Scripture reading in the family fellowship. Historical books, prophets, Gospels, Epistles, and Revelation are read and heard as God's Word in their context. They set the listening fellowship in the midst of the wonderful world of revelation of the people of Israel with its prophets, judges, kings, and priest, its wars, festivals, sacrifices, and sufferings. The fellowship of believers is woven into the Christmas story, the baptism, the miracles and teaching, the suffering, dying, and rising again of Jesus Christ. It participates in the very events that occurred on this earth for the salvation of the world, and in doing so receives salvation in Jesus Christ.
Consecutive reading of Biblical books forces everyone who wants to hear to put himself, or to allow himself to be found, where God has acted once and for all for the salvation of men. We become a part of what once took place for our salvation. Forgetting and losing ourselves, we, too, pass through the Red Sea, through the desert, across the Jordan into the promised land. With Israel we fall into doubt and unbelief and through punishment and repentance experience again God's help and faithfulness. All this is not mere reverie but holy, godly, reality. We are torn out of our own existence and set down in the midst of the holy history of God on earth. There God dealt with us, and there He still deals with us, our needs and our sins, in judgment and grace. It is not that God is the spectator and sharer of our present life, howsoever important that is; but rather that we are the reverent listeners and participants in God's actions in the sacred story, the history of the Christ on earth. And only in so far as we are there, is God with us today also.
A complete reversal occurs. It is not in our life that God's help and presence must still be proved, but rather God's presence and help have been demonstrated for us in the life of Jesus Christ. It is in fact more important for us to know what God did to Israel, to His Son Jesus Christ, than to seek what God intends for us today. The fact that Jesus Christ died is more important than the fact that I shall die, and the fact that Jesus Christ rose from the dead is the sole ground of my hope that I, too, shall be raised on the Last Day. Our salvation is "external to ourselves." I find no salvation in my own life history, but only in the history of Jesus Christ. Only he who allows himself to be found in Jesus Christ, in his incarnation, his Cross, and his resurrection, is with God and God with him.
In this light the whole devotional reading of the Scriptures becomes daily more meaningful and salutary. What we call our life, our troubles, our guilt, is by no means all of reality; there in the Scriptures is our life, our need, our guilt, and our salvation. Because it pleased God to act for us there, it is only there that we shall be saved. Only in the Holy Scriptures do we learn to know our own history. The God of Abraham, Isaac, and Jacob is the God and Father of Jesus Christ and our Father.
We must learn to know the Scriptures again, as the Reformers and our fathers knew them. We must not grudge the time and the work that it takes. We must know the Scriptures first and foremost for the sake of our salvation.
