Charles H. Spurgeon on Psalms 25:8

Good and upright is the Lord: therefore will he teach sinners in the way. Here the goodness and rectitude of the divine character are beheld in friendly union; he who would see them thus united in bonds of perfect amity must stand at the foot of the cross and view them blended in the sacrifice of the Lord Jesus. It is no less true than wonderful that through the atonement the justice of God pleads as strongly as his grace for the salvation of the sinners whom Jesus died to save. Moreover, as a good man naturally endeavours to make others like himself, so will the Lord our God in his compassion bring sinners into the way of holiness and conform them to his own image; thus the goodness of our God leads us to expect the reclaiming of sinful men. We may not conclude from God's goodness that he will save those sinners who continue to wander in their own ways, but we may be assured that he will renew transgressors' hearts and guide them into the way of holiness. Let those who desire to be delivered from sin take comfort from this. God himself will condescend to be the teacher of sinners. What a ragged school is this for God to teach in! God's teaching is practical; he teaches sinners not only the doctrine but the way.
