Vow to God and keep it: especially strive in performing the solemn vow of your baptism, and the covenant which you renew in the Lord's Supper
Variance and discord with men will not stand with your peace with God. If you love God, you will love men also, for God's image or else for his commandments sake.
Use the world as not using it, and your prosperity and liberty to be bettered by them. That is not gained which is got with the loss of your soul, and the soul is exchanged for a handful of the world, when it is not got and held: 1. in Christ restoring it, 2. with Christ the chief gain, 3. for Christ the Lord of it.
