For it is God which worketh in you both to will and to do of his good pleasure.
Ver. 13. For it is God which worketh] Therefore work out, &c. As acti agentes, moti moventes, as the inferior orbs move, as acted by the superior. When God hath turned, and doth touch us, we must move; and while the Spirit imbreathes us, we must turn about like the mill.
To will and to do] Sub laudibus naturae latent inimici gratiae, saith Augustine; who stood so much for grace, that the schoolmen say he yielded too little to freewill. That we live is the gift of the gods (saith Seneca); that we live well, is of ourselves. A base speech! So Cicero (De Nat. Deor.), Iudicium hoc omnium mortalium est fortunam a Deo petendam, a seipso sumendam sapientiam. For which impious sentence Augustine saith of him, Eum, ut faceret homnes liberos, fecisse sacrileges. (De Civ. Dei, 5.)
