Matthew Henry on Psalms 119:65-72

However God has dealt with us, he has dealt with us better than we deserve; and all in love, and for our good. Many have knowledge, but little judgment; those who have both, are fortified against the snares of Satan, and furnished for the service of God. We are most apt to wander from God, when we are easy in the world. We should leave our concerns to the disposal of God, seeing we know not what is good for us. Lord, thou art our bountiful Benefactor; incline our hearts to faith and obedience. The psalmist will go on in his duty with constancy and resolution. The proud are full of the world, and its wealth and pleasures; these make them senseless, secure, and stupid. God visits his people with affliction, that they may learn his statutes. Not only God's promises, but even his law, his percepts, though hard to ungodly men, are desirable, and profitable, because they lead us with safety and delight unto eternal life.
