But I have not been called to come in unto the king these thirty days.
Providence tries faith
Thus it is that Providence sometimes frowns on the cause of His Church and people, by not only exposing them to imminent danger, but by shutting up all the ordinary avenues of escape, so that there appears no evasion for them. This proves a severe trial to their faith, but affords an opportunity for displaying His own wisdom and mercy in their ultimate deliverance. (T. McCrie.)
The darker aspect, of providence
We have here an illustration of what is not unfrequently observable in the arrangements of the Divine providence--that the affairs of God’s people assume a darker and darker aspect, just before a favourable interposition comes--in order, no doubt, to make the truth more palpable, that it is by His hand that their deliverance, is wrought out, and that therefore they should never distrust Him, nor think that He has forgotten to be gracious. (A. B. Davidson, D. D.)
Access to God without fear
It is indeed with the Great King you have to deal, and life and death are at His disposal; but you may go to Him without fear, if you go with a true heart. There was all the formality of priestly services under the law, between the worshippers and Jehovah, to make them feel that they could not come nigh personally; just as there were functionaries to prevent Esther from coming into the presence of the king, when she merely felt the wish to do so. Now, however, God invites us to come to Him at all times, and what prevents us from having full communion with Him is not our personal unworthiness, but our unbelief. (A. B. Davidson, D. D.)
