To be the first to speak in the presence even of human beings who know more than us, is to bring shame on ourselves, for we evidently desire to hear the sound of our own voices more than to have light shed on the matter. But in coming to God, the situation is far more urgent because our eternal destiny is at stake. Better to say nothing than to start presenting feeble excuses. If we must speak, let it be like Job, who spoke only to confess the extent of his sin and to beg for mercy. All other words are superfluous. Let us only acknowledge our ignorance and the glory of God, and let us admit that we can know nothing about God beyond what he has told to us about himself. Let us say nothing about our own goodness. Let us not speak of our knowledge or our gifts or accomplishments, for all fall short of his standard, and anything good that we have, came from God in the first place.
There must be a first time for each one of us when we come to God. When we first see our sin and the awful consequences of it, that we are on the road to hell and sin will drag us down to the grave eternally, we tremble at our predicament. As the Spirit humbles us and shows us that the grace of God in Jesus Christ is our only hope, we repent of our sins and come to the only Saviour. It is this initial approach to God that Solomon has in mind here.
