Charles H. Spurgeon on Psalms 116:5

Gracious is the Lord, and righteous. In hearing prayer the grace and righteousness of Jehovah are both conspicuous. It is a great favour to hear a sinner's prayer, and yet since the Lord has promised to do so, he is not unrighteous to forget his promise and disregard the cries of his people. The combination of grace and righteousness in the dealings of God with his servants can only be explained by remembering the atoning sacrifice of our Lord Jesus Christ. At the cross we see how gracious is the Lord and righteous. Yea, our God is merciful, or compassionate, tender, pitiful, full of mercy. We who have accepted him as ours have no doubt as to his mercy, for he would never have been our God if he had not been merciful. See how the attribute of righteousness seems to stand between two guards of love: —gracious, righteous, merciful. The sword of justice is scabarded in a jewelled sheath of grace.
