Albert Barnes Commentary Psalms 107:43

"Whoso is wise will give heed to these things; And they will consider the lovingkindnesses of Jehovah." — Psalms 107:43 (ASV)

Whoever is wise - All who are truly wise. That is, all who have a proper understanding of things, or who are disposed to look at them rightly.

And will observe these things - Will attentively consider them; will reason upon them correctly; will draw just conclusions from them; will allow them to produce their proper impression on the mind. The meaning is that these things would not be understood at a glance, or by a hasty and cursory observation, but that all who would take time to study them would see in them such proofs of wisdom and goodness that they could not fail to come to the conclusion that God is worthy of confidence and love.

Even they will understand the lovingkindness of the Lord - They will perceive that God is a merciful Being; that He seeks the welfare of the universe; that He desires the good of all; that the whole system is so arranged as to be adapted to secure the greatest good in the universe.

No one can study the works of God, or mark the events of His providence, without perceiving that there are innumerable arrangements which have no other end than to produce happiness. These arrangements can be explained only on the supposition that God is a benevolent Being, and they would not exist under the government of a malevolent being.

And, although there are things which seem to be arrangements to cause suffering, and although sin and misery have been allowed to come into the world, we are not yet in a position to show that these events are, in some way, inconsistent with God's desire to promote the happiness of the universe. It may also be that there is some explanation, at present too high for us, which will demonstrate that the principle of benevolence is applicable to all the works of God.

Meanwhile, where we can - as we can in numberless cases - see the proofs of benevolence, let us praise God. Where we cannot, let us silently trust Him, and believe that there will yet be some way in which we may see this as the angels now see it, and, like them, praise Him for what now seems to us to be dark and incomprehensible.

There is an eternity before us in which to study the works of God, and it would not be strange if in that eternity we may learn things about God which we cannot understand now. Nor would it be strange if, in that eternity, things now as dark as midnight to us may be made as clear as noonday. How many things incomprehensible to us in childhood become clear in later years!
