"Let us beware of tinkering with our inner life, hoping ourselves to rend the veil. God must do everything for us. Our part is to yeild and trust. We must confess, forsake, repudiate the self-life, and then reckon it crucified." (The Pursuit of God, A.W. Tozer)
So it all comes down to surrender. We surrender all of ourselves and our wills to God. The song below by Nicole Brown sums it all up:
God of grace, God of mercy;
God of hope, God of truth.
You are my light and my salvation
Whom shall I fear?
I shall not be moved.
I bring my life, I bring my choices,
I bring my mind, Lord I bring my heart.
Here I am, in full surrender
I give you all, take every part.
Here I come through the veil;
Here I stand, I seek your face,
Here I am, my life laid bare before You.
I'm lost without You.
