LSB #587 "I Know My Faith Is Founded"

Biblical citations in the hymnal:  2 Timothy 1:12, John 17:8, Luke 17:5, 1 Peter 1:3-9

2 Timothy 1:12:  "which is why I suffer as I do.  But I am not ashamed, for I know whom I have believed, and I am convinced that he is able to guard until that Day what has been entrusted to me."

John 17:8:  "'For I have given them the words that you gave me, and they have received them and have come to know in truth that I came from you; and they have believed that you sent me.'"

Luke 17:5:  "The apostles said to the Lord, 'Increase our faith!'"

1 Peter 1:3-9:  "3 Blessed be the God and Father of our Lord Jesus Christ!  According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4 to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, 5 who by God's power are being guarded through faith for a salvation ready to be revealed in the last time.  6 In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, 7 so that the tested genuineness of your faith - more precious than gold that perishes though it is tested by fire - may be found to result in praise and glory and honor at the revelation of Jesus Christ.  8 Though you have not seen him, you love him.  Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, 9 obtaining the outcome of your faith, the salvation of your souls."

I know my faith is founded

On Jesus Christ, my God and Lord;

And this my faith confessing,

Unmoved I stand on His sure Word.

Our reason cannot fathom

The truth of God profound;

Who trusts in human wisdom

Relies on shifting ground.

God's Word is all-sufficient,

It makes divinely sure;

And trusting in its wisdom,

My faith shall rest secure.

Increase my faith, dear Savior,

For Satan seeks by night and day

To rob me of this treasure

And take my hope of bliss away.

But, Lord, with You beside me,

I shall be undismayed;

And led by Your good Spirit,

I shall be unafraid.

Abide with me, O Savior,

A firmer faith bestow;

Then I shall bid defiance

To ev'ry evil foe.

In faith, Lord, let me serve You;

Though persecution, grief, and pain

Should seek to overwhelm me,

Let me a steadfast trust retain;

And then at my departure,

Lord, take me home to You,

Your riches to inherit

As all You said holds true.

In life and death, Lord, keep me

Until Your heav'n I gain,

Where I by Your great mercy

The end of faith attain.

The verse from John 17 seems to appear in the first verse, although lines like "Unmoved I stand on His sure Word" and "Who trusts in human wisdom / Relies on shifting ground" bear more resemblance to Matthew 7:24-27:  "24 'Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock.  25 And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock.  26 And everyone who hears these words of mine and does not do them will be like a foolish man who built his house on the sand.  27 And the rain fell, and the floods came, and the winds blew and beat against that house, and it fell, and great was the fall of it.'"

Luke 17:5 appears twice in the second verse:  "Increase my faith, dear Savior" and "A firmer faith bestow."  (Incidentally, "night and day" is a merism.)

The last verse seems to combine 2 Timothy 1:12 and 1 Peter 1:3-9.
