As we are about to enter upon the study of this book, I want to say first a few things of an introductory character. I suppose there is no portion of Holy Scripture that has meant more to the people of God, particularly to tried and afflicted believers down through both the Jewish and Christian centuries, than the book of Psalms. Of course the worship expressed in this book does not rise to the full character of Christian worship as in this present dispensation of the grace of God. As we read the Psalms we need to remember that when they were written our Lord Jesus had not yet become incarnate; consequently, redemption had not been effected, and so the veil was still unrent. God, as it were, was shut away from man, and man was shut out from God; and so the worshiper of Old Testament times gives expression to certain things that would not be suitable from the lips of an instructed worshiper in this present age of grace. David prays, "Take not Thy Holy Spirit from me." No well instructed Christian would pray that today, for we know now that we have received the Holy Spirit to abide with us forever. We have been sealed by the Holy Spirit until the redemption of the purchased possession. And then there are a great many of the prayers in the book of Psalms that imply a hidden God. But today God has come out into the light, since our Lord Jesus, by His sacrificial death upon the Cross, has rent the veil and opened up the way into the immediate presence of God for poor sinners and enabled God to come out to man in all the perfection of His glorious Person.
