Psalms 92:15

To show that the Lord is upright, &c. That he is true to his promises, and faithful to every word that he hath spoken, and therefore does not leave nor forsake those that cleave to him, but carries on the work which he has begun. As it is by his promises that believers first partake of a divine nature, so it is by his promises that that divine nature is preserved and maintained, and therefore the power it exerts is an evidence that the Lord is upright, and such he will show himself to be with an upright man, Psalms 18:25. He is my rock I have chosen him for my rock, on which to build my confidence and hopes for time and eternity, and in the clefts of which to take shelter in the time of danger: and I have found him a rock, strong and steadfast, and his word firm and stable. And there is no unrighteousness in him He is as able, and will be as kind, as his word represents him to be. All that ever trusted in God have found him faithful and all-sufficient, and none were ever made ashamed of their hope in him. He is just and upright in his dealings with his intelligent creatures, “immoveable in his counsels, and determined to punish the wicked and reward the good; so that, when his proceedings shall come to be unfolded at the last day, it will appear to men and angels that there is no unrighteousness in him.” Horne.
