John 16:30, 51: What must I do to be saved?...Believe, &c

Author of our sure salvation,
Author of our faith Thou an,
Call me out of condemnation,
Sprinkle with Thy blood my heart,
Give the faith that moves the mountain,
Pardon'd, saved by faith alone,
Lead me through that open fountain
To Thine everlasting throne.
O that I could but act on Thee
One simple act of faith Divine!
Saviour I then from sin set free
Should truly call Thy fulness mine:
Believing through Thy grace alone
My pardon truly I receive;
And if I once Thy love have known,
Redeem'd I may for ever live.
O help my unbelieving heart
To pant, and break, and straggle through j
Till Thou the faithful power impart,
Thou know'st I know not what to do';
I only can of Thee inquire
What must I do to' escape from sin?
Answer; fulfil Thine own desire,
And cleanse my heart by entering in.
Fast bound in chains of hellish night,
I still for full redemption groan;
Arise, Thou everlasting Light,
And send a ray of glory down,
Emit that emanation pure
Which only can my griefs remove,
My fears disperse, my evils cure,
And tell my soul that God is love.
Alas, what shall, or can I do
But what I have already done?
My labour vain again renew,
My search after a God unknown?
Were there a mean 'twixt heaven and hell.
I could my anxious hopes forego:
But if with God I cannot dwell,
I must with fiends in endless woe.

What must I do? who hears my heart,
God, the incarnate God reply,
And save me through His own desert
Before the second death I die;
Through faith in His atoning blood
Which purges all iniquity,
Which for a world of sinners flow'd,
Mercy there is reserved for me.
