2 Thessalonians 3:4

As if the apostle had said, "Although. gave you the assurance of God's faithful readiness, according to his promise, to do every thing that is requisite on his part, in order to your establishment in holiness, and preservation from sin; yet you must not, you cannot, expect the assistance of God, except you also add your own endeavours, as. have commanded; and accordingly,. have good confidence, that what. command you in the Lord, or by the authority of the Lord, both now and hereafter, at all times, shall be performed by you."

Where note, The character of that obedience which the gospel directs; it must be universal and perpetual: Ye do all things that. command you, and. have confidence that ye will do.
