Hebrews 5:9

And being made perfect,.... In his obedience, through sufferings; having completed his obedience, gone through his sufferings, and finished his sacrifice, and being perfectly glorified in heaven:he became the author of eternal salvation unto all them that obey him; the salvation Christ is the author of is "eternal"; it was resolved upon from eternity, and contrived in it; it was secured in the everlasting covenant, in which not only a Saviour was provided, but blessings both of grace and glory: and it is to eternity; and stands distinguished from a temporal salvation, and is opposed to eternal damnation; it is the salvation of the soul, which is immortal; and it takes in both grace and glory, which are of a durable nature; and the continuance of it is owing to the abiding and lasting virtue of Christ's person, blood, and righteousness: and Christ is the cause or author of this salvation, by his obedience and sufferings; by obeying the precept, and bearing the penalty of the law; by the price of his blood, and by the power of his arm; by his death and by his life; by his sacrifice on the cross, and by his intercession in heaven; by bestowing grace here, and glory hereafter: this shows that salvation is done, and that Christ is the sole author of it, and that all the glory of it should be given to him; and those to whom he is the author of salvation, are such as hearken to the voice of his Gospel, and obey hin in his ordinances.
