8. _I know thy works._ See Notes on ch. ii. 2. ¶ _Behold, I have set before thee an open door._ Referring to his authority as stated in ver. 7. The “open door” here evidently refers to the enjoyment of some privilege or honour; and, so far as the _language_ is concerned, it may refer to any one of the following things: either, (1) the ability to do good――represented as the “opening of the door.” Comp. Ac. xiv. 27; 1 Co. xvi. 9; 2 Co. ii. 12; Col. iv. 3. (2) The privilege of access to the heavenly palace; that is, that they had an abundant opportunity of securing their salvation, the door being never closed against them by day or by night. Comp. Re. xxi. 25. Or (3) it may mean that they had before them an open way of egress from danger and persecution. This latter Professor Stuart supposes to be the true meaning; and argues this because it is immediately specified that those Jewish persecutors would be made to humble themselves, and that the church would but lightly experience the troubles which were coming upon the world around them. But the more natural interpretation of the phrase “an open door” is that it refers to access _to_ a thing rather than egress _from_ a thing; that we may come to that which we desire to approach, rather than escape from that which we dread. There is no objection, it seems to me, to the supposition that the language may be used here in the largest sense――as denoting that, in regard to the church at Philadelphia, there was no restraint. He had given them the most unlimited privileges. The temple of salvation was thrown open to them; the celestial city was accessible; the whole world was before them as a field of usefulness, and anywhere, and everywhere, they might do good, and at all times they might have access to the kingdom of God. ¶ _And no man can shut it._ No one has the power of preventing this, for he who has control over all things concedes these privileges to you. ¶ _For thou hast a little strength._ This would imply that they had not _great_ vigour, but still that, notwithstanding there were so many obstacles to their doing good, and so many temptations to evil, there still remained with them some degree of energy. They were not wholly dead; and as long as that was the case, the door was still open for them to do good. The words “little strength” may refer either to the smallness of the _number_――meaning that they were few; or it may refer to the spiritual life and energy of the church――meaning that, though feeble, their vital energy was not wholly gone. The more natural interpretation seems to be to refer it to the latter; and the sense is, that although they had not the highest degree of energy, or had not all that the Saviour desired they should have, they were not _wholly_ dead. The Saviour saw among them the evidences of spiritual life; and in view of that he says he had set before them an open door, and there was abundant opportunity to employ all the energy and zeal which they had.
