LSB #664 "Fight the Good Fight"

Biblical citations in the hymnal:  1 Timothy 6:12, 1 Corinthians 9:24-27, 1 Peter 5:7, Psalm 55:22

1 Timothy 6:12:  "Fight the good fight of the faith.  Take hold of the eternal life to which you were called and about which you made the good confession in the presence of many witnesses."

1 Corinthians 9:24-27:  "24 Do you not know that in a race all the runners run, but only one receives the prize?  So run that you may obtain it.  25 Every athlete exercises self-control in all things.  They do it to receive a perishable wreath, but we an imperishable.  26 So I do not run aimlessly; I do not box as one beating the air.  27 But I discipline my body and keep it under control, lest after preaching to others I myself should be disqualified."

1 Peter 5:7:  "casting all your anxieties on him, because he cares for you."

Psalm 55:22:  "Cast your burden on the LORD, and he will sustain you; he will never permit the righteous to be moved."

Fight the good fight with all your might;

Christ is your strength, and Christ your right.

Lay hold on life, and it shall be

Your joy and crown eternally.

Run the straight race through God's good grace;

Lift up your eyes, and seek His face.

Life with its way before us lies;

Christ is the path, and Christ the prize.

Cast care aside, lean on your guide;

His boundless mercy will provide.

Trust, and enduring faith shall prove

Christ is your life and Christ your love.

Faint not nor fear, His arms are near;

He changes not who holds you dear;

Only believe, and you will see

That Christ is all eternally.

The cited passages are easy to distinguish in the hymn text.  1 Timothy 6:12 appears in the first verse; 1 Corinthians 9:24-27 appears in the second verse; and 1 Peter 5:7 and Psalm 55:22 both appear in the third verse.

The first half of the line "He changes not who holds you dear" in the fourth verse may be drawn from Hebrews 13:8:  "Jesus Christ is the same yesterday and today and forever."
