Your Definition of "True Repentance" please

[Esaias]

You have longed for sweet peace,
And for faith to increase,
And have earnestly, fervently prayed;
But you cannot have rest,
Or be perfectly blest,
Until all on the altar is laid.
Refrain:
Is your all on the altar of sacrifice laid?
Your heart does the Spirit control?
You can only be blest,
And have peace and sweet rest,
As you yield Him your body and soul.
Would you walk with the Lord,
In the light of His word,
And have peace and contentment alway?
You must do His sweet will,
To be free from all ill,
On the altar your all you must lay.
Oh, we never can know
What the Lord will bestow
Of the blessings for which we have prayed,
Till our body and soul
He doth fully control,
And our all on the altar is laid.
Who can tell all the love
He will send from above,
And how happy our hearts will be made;
Of the fellowship sweet
We shall share at His feet,
When our all on the altar is laid.
