Ephesians 1:5

Having predestinated us
Predestination, taken in a large sense, includes both election and reprobation, and even reaches to all affairs and occurrences in the world; to the persons, lives, and circumstances of men; to all mercies, temporal or spiritual; and to all afflictions, whether in love or in wrath: and indeed providence, or the dispensations of providence, are no other than the execution of divine predestination; but here it is the same with election, and is concerned with the same persons, and has regard to a special blessing, the elect are appointed to, as follows;

unto the adoption of children by Jesus Christ unto himself;
by which is meant, either the grace of adoption, which is an act of the Father's love, a blessing provided and secured in the covenant of grace; and is of persons to an inheritance, to which they have no legal right; and is entirely free, there being no need on the adopter's part, and no worth on the part of the adopted: or rather the inheritance they are adopted to; which exceeds all others, is incorruptible, undefiled, and fades not away; and lies among the saints in light, and belongs to all the children of God: and this they are predestinated unto by God the Father, who takes them into his family, puts them among the children, and gives them a goodly heritage: and that "by Jesus Christ"; or through him; for both the grace of adoption, and the kingdom and glory they are adopted to, come by and through him as Mediator; through his espousing their persons, assuming their nature, and redeeming them from under the law and its curses; through his giving them a power and privilege openly to be the sons of God; and through faith in him, whereby they are manifestly such: the phrase "unto himself", either refers to God the Father, who has chosen, set apart, formed and reserved his people and children for himself, for his peculiar treasure, and for his own glory; or to Jesus Christ, that he might have some brethren, and they be conformed to him, and he be the firstborn among them, and in all things have the pre-eminence; and that they might be with him, and behold his glory, and he be glorified in them: and this act of divine predestination was

according to the good pleasure of his will:
the will of God is the rule of all his actions, and of all his acts of grace and goodness; and the good pleasure of it appears in the predestination of men to grace and glory: and from hence it is manifest, that foreseen faith, holiness, and good works, are excluded from being the moving cases of predestinating grace; and that it is wholly to be resolved into the good will and pleasure of God; the view in it being entirely as follows,
