Psalm 119:165

Great peace have those who love your law;

nothing can make them stumble.

"Great peace have they which love thy law. It dwells not with those who perfectly keep the law, for where would such men be found? but with those who love it, whose hearts and hands are made to square with its precepts and demands. These men are ever striving, with all their hearts, to walk in obedience to the law, and though they are often persecuted they have peace, great peace; for they have learned the secret of the reconciling blood, they have felt the power of the comforting Spirit, and they stand before the Father as men accepted. The Lord has given them to feel his peace, which passed all understanding. They have many troubles, and are likely to be persecuted by the proud, but their usual condition is that of deep calm-- a peace too great for this world to break. And nothing shall offend them, or, "shall really injure them." "All things work together for good to them that love God, to them who are the called according to his purpose." It must needs be that offences come, but these lovers of the law are peacemakers, and so they neither give nor take offence. That peace which is founded upon conformity to God's will is a living and lasting one, worth writing of with enthusiasm, as the Psalmist here does."
