Matthew 10: Can a minister complain

Can a minister complain,
Can he ever want success?
If by each repulse he gain
Peace, confirm'd abundant peace;
If the peace which sinners spurn,
Heavenly, inconceivable.
Into his own breast return,
There with Christ for ever dwell?

Profit every way we find,
We, fi-om whom our gracious Lord
Only asks a willing mind
Simply to declare His word:
Jesus, if employ'd by Thee,
Thou shalt teach us what to say,
Bid us prove our ministry,
Give both will and power to' obey.
