The call to trust implies imperiled trust.
This and the following verses were, apparently, sung as responses. This explains the repetition of the same idea. The scornful taunts of the surrounding peoples might have had a serious influence on Jehovah's servants. It might have taken all heart out of them. Probably many of the weaker ones did flag under the discouragements, and so there was a real need of this pleading of the psalmist for full and even rejoicing trust in God. The confidence felt by one man will often inspire the confidence of others. When one man can see God plainly working as Helper and Defender, he, in a very wonderful way, opens the eyes of others to see the same signs of Divine presence and power. Our trust in God passes from one to another, even as does an epidemic disease. And it may also be shown how often psalm and song help us to fetch back imperiled trust. Treating the case of the restored exiles as illustrative, we may see how our trust in God may now be imperiled—
I. BY GOD'S UNFULFILLED PROMISES. Some of God's promises really belong to our future, and we have no right to look for their present fulfillment; but such is the restlessness of man, that he persists in thinking he ought to have everything now. And as he cannot, he readily regards some of God's promises as unfulfilled. So through long ages men expected the promised Messiah, and often lost their faith and dimmed their hope because he did not come. But God's promises never are unfulfilled. It is only this—he has our whole lives to work in, he has all the ages to work in. Compare our Lord's saying, "My time is not yet come, but your time is always ready." Trust should make a treasure of the promises.
II. BY GOD'S INCOMPLETELY FULFILLED PROMISES. It is harder to keep trust when a promise has begun to be fulfilled, and has been checked in the fulfillment, than when it is altogether delayed. It was harder for the exiles to look on the new foundations of the temple than on the old ruins. There is no feature of Divine discipline that so severely tries our power to keep on trusting, as this checking of blessings that have begun to be bestowed; this asking us to accept of incomplete fulfillments.
III. BY GOD'S MISUNDERSTOOD PROMISES. So often we take God to promise what we wish him to promise, rather than what he does promise. Then we raise unreason able expectations, and get unreasonably depressed when they are not fulfilled. God may test and try our trust, but he never puts it in peril; we do that when we cannot wait, and persist in misunderstanding.—R.T.
