Psalms 119:171 - Albert Barnes' Notes on the Bible

My lips shall utter praise, when thou hast taught me thy statutes - The sentiment here is the same as in Psalms 119:7. The language is varied, but the meaning here, as in that verse, is, I will praise thee in proportion as I learn thy precepts or thy law. The more I learn of thy will, the more I will praise thee. I shall see more for which to offer praise and adoration, and I shall be more and more inclined to praise and adore time. Each new degree of knowledge will excite a corresponding desire to praise thee. This will be true of all who love God, while this life lasts, and forever. The ever-increasing knowledge of God will excite ever-increasing praise; and as God is infinite and eternal, it follows that the increase of knowledge and of happiness, in those who are saved, will be eternal. These things will go hand in hand forever and ever.
