changeableness, that they will not stand to the bargain, but break and
return with the dog to the vomit; for Christ hath engaged to bring all
through that come unto him; he will raise them up at the last day, John
vi. 40; he will present them to himself holy and without spot or
wrinkle, or any such thing, Eph. v. The covenant is fully provided with
promises to stop the mouth of that objection. Nor can they object the
difficulty or impossibility of believing; for that is Christ's work

not with confidence cast themselves upon him; yet if they can hunger and

hunger and thirst for him, yet if they be willing, all is well. Are they
willing that Christ save them in his way, and therefore willingly give
themselves over to him, and are willing and content that Christ, by his
Spirit, work more hunger in them, and a more lively faith, and work both
to will and to do according to his own good pleasure, it is well.

Christ only: corrupt nature would not have the man wholly denying
himself, and following Christ only. And hence many lose themselves, and
lose all; because, with the Galatians, they would mix the law and the
gospel together; do something themselves for satisfaction of justice,
