It is acknowledged, that many pastors ought to have become missionaries before they were settled--that the present amazing disproportion between settled ministers at home, and missionaries abroad, ought never to have existed. To argue so plain a case would be a waste of breath. How then can the fact of having wandered from duty excuse one from the performance of it? To-day, it is the duty of Jonah to go to Nineveh. To-morrow, he has engaged his passage to Tarshish, has paid his fare, has gone down into the sides of the ship, and is quietly at rest. Is he therefore excused? To-day, the command of Christ presses upon me the obligation to go to the heathen. To-morrow, leaving out of mind this command, which still applies in all its force, I enter into an obligation with a particular church to take upon me its pastoral care: which obligation is binding? The last, do you say? Can I then thus easily thrust aside the Saviour's last and most impressive command? Can I, by such a course, shield myself effectually from its further application? I have yet to learn, that by any change of place or circumstances we can free ourselves from the weight of the Saviour's injunction. I mean not to assert, that all who ought to have become missionaries before they were settled, ought to become so now. Some have entirely hedged up their way; and though they may have been disobedient in doing so, yet deep regret and sincere repentance is all the reparation they can now make. But those who ought to have gone to the heathen, and before whom the door is still open for going, _such_ should still become missionaries, and on the obvious principle, that it is better to do our duty late than not to do it all. The mere plea of being a pastor is not a sufficient excuse; and it is losing too, continually, more and more of its force. It is a wonder that it should be relied upon so much as a _quietus_, since, in the present age, the residence of a pastor is very transient and uncertain.
