9 For a great door and effectual is opened unto me, and there are many adversaries.
9 because a great door for effective work has opened to me, and there are many who oppose me.
9 for a wide door for effective work has opened to me, and there are many adversaries.
9 A huge door of opportunity for good work has opened up here. (There is also mushrooming opposition.)
9 For a great and effective door has opened to me, and there are many adversaries.
9 There is a wide-open door for a great work here, although many oppose me.
Matthew Henry's Commentary on 1 Corinthians 16:9
Commentary on 1 Corinthians 16:1-9
(Read 1 Corinthians 16:1-9)
The good examples of other Christians and churches should rouse us. It is good to lay up in store for good uses. Those who are rich in this world, should be rich in good works, James 4:15. Adversaries and opposition do not break the spirits of faithful and successful ministers, but warm their zeal, and inspire them with fresh courage. A faithful minister is more discouraged by the hardness of his hearers' hearts, and the backslidings of professors, than by the enemies' attempts.
