Be on fire

The Kingdom of Heaven is like a great treasure hidden in a field.

When a man discovers the treasure,
He goes and sells all he has and purchases the field with great joy.

Similarly, when you discover your purpose,
put all your strength into the work of the purpose.

Be on fire.

Be zealous.
Be filled full of enthusiasm for the work's sake.

Be not slack or lukewarm.
Give it your all and all.
