We use to say, He will have his own will, do all we can.

If a man be willing, then any argument shall be matter of encouragement; but if unwilling, then any argument shall give discouragement.

The saints of old, they being willing and resolved for heaven, what could stop them?
Could fire and fagot, sword or halter, dungeons, whips, bears, bulls, lions, cruel rackings, stonings, starvings, nakedness?
So willing had they been made in the day of His power.

And see, on the other side, the children of the devil, because they are not willing, how many shifts and starting-holes they will have! I have married a wife; I have a farm; I shall offend my landlord; I shall lose my trade; I shall be mocked and scoffed at, and therefore I cannot come.

But, alas! the thing is, they are not willing.
