Charles H. Spurgeon on Psalms 143:10

Teach me to do thy will, etc. We are inclined and enabled to good by the sanctifying Spirit. In the Christian religion, not only the precepts are good, but there goeth along with them the power of God to make us good. Teach me to do thy will; for thou art my God: thy Spirit is good. The Spirit's direction hath strength joined with it. And he is a good Spirit, as he doth incline us to good. The Spirit is the only fountain of all goodness and holiness: Ne 9:20, "Thou gavest also thy good Spirit to instruct them." Why is he so often called the good Spirit, but that all his operations tend to make men good and holy? Eph 5:9, "The fruit of the Spirit is in all goodness and righteousness and truth." —Thomas Manton.
