There are the sent and the went.  The sent are those who were called by God and they obeyed His Voice.  The went are those who were never sent by God but they went anyway.  The went are the majority by far.

Jeremiah 23:21 I have not sent these prophets, yet they ran: I have not spoken to them, yet they prophesied. *

Jeremiah 29:9 For they prophesy falsely to you in my name: I have not sent them, says Jehovah.

When God leads, there is no room for ego, profit-taking, prestige, or jockeying for position.  The way of the Spirit is the humble way.  In this age where the immature in Christ are eager to be set up on high as leaders, this is an important message: "Wait until I send you, says the Lord."  We are seeing so many who "don't care about money," so they demand that other people support them while they "do really fun ministry."  They can't take on the normal responsibility that even the unbelievers take on, yet they want to be leaders of the flock of God.

"Stay there until I tell you" Matt. 2; 13

I'll stay where you've put me, I will, dear Lord, though I wanted so badly to go;
I was eager to march with the "rank and file", Yes I wanted to lead them, you know
I planned to keep step to the music loud, to cheer when the banner unfurled,
To stand in the midst of the fight straight and proud, but I'll stay where you've put me.

I'll stay where you've put me; I'll work, dear Lord, though the field be narrow and small,
And the ground be neglected, and stones lie thick, and there seems no life at all.
The field is your own, only give me the seed, I'll sow it with never a fear;
I'll till the dry soil while I wait for the rain, and rejoice when the green blades appear;
I'll work where you've put me.

I'll stay where you've put me; I will, dear Lord; I'll bear the day's burden and heat
Always trusting you fully; when sunset has come, I'll lay stalks at your feet.
And then, when my earth work is ended and done, in the light of eternity's glow,
Life's record all closed, I surely will find it was better to stay than to go;
I'll stay where you've put me.
