Psalms 119:45

The next verse may be read as expressing a desire that he might walk. Be this as it may, we retain the commonly received reading, That David exults at the thought of his path becoming plain and easy, in consequence of his seeking diligently after God’s precepts; that is, to walk at ease The ways of men are frequently rugged and obstructed, because they themselves lay various stumblingblocks in them, or entangle themselves in many inextricable windings. Hence it comes to pass, that while none will submit to the word of God as their rule, every man endures the punishment legitimately due to such arrogance. On all sides God lays snares for us, puts pitfalls in our way, causes us to fall in with paths broken and rugged, and at last shuts us up in a bottomless pit: and by how much the more politic a mart is, by so much the more will he meet with obstructions in his path.

This verse teaches us that, if any man yield implicit obedience to God, he will receive this as his reward, that he shall walk with a calm and composed mind; and should he meet with difficulties, he will find the means of surmounting them. The faithful, however readily and submissively they give themselves up to God, may happen to find themselves involved in perplexity; nevertheless, the end contemplated by Paul is accomplished, that though they be in trouble and toil, yet they do not continue in irremediable distress, because it is the duty (so to speak) of God to point out a way for them where there seems to be no way, (2 Corinthians 4:8.) Moreover, when grievously oppressed, even then they walk at ease, for they commit the doubtful issue of events to God in such a manner, that, having him for their guide, they have no doubt they will come out boldly from the depths of distress.
