Here’s an excellent hymn John Newton wrote based on the teaching of “simultaneously saint and sinner” in Galatians 5:17: For the flesh desires what is contrary to the Spirit, and the Spirit what is contrary to the flesh. They are in conflict with each other, so that you are not to do whatever you want (NIV).
Strange and mysterious is my life,
What opposites I feel within!
A stable peace, a constant strife,
The rule of grace, the pow’r of sin:
Too often I am captive led,
Yet daily triumph in my Head.
I prize the privilege of prayer,
But o! what backwardness to pray!
Though on the LORD I cast my care,
I feel its burden every day:
I seek his will in all I do,
Yet find my own is working too.
I call the promises my own,
And prize them more than mines of gold;
Yet though their sweetness I have known,
They leave me unimpressed and cold
One hour upon the truth I feed,
The next I know not what I read.
I love the holy day of rest,
When Jesus meets his gathered saints;
Sweet day, of all the week the best!
For its return my spirit pants:
Yet often, through my unbelief,
It proves a day of guilt and grief.
While on my Savior I rely,
I know my foes shall lose their aim;
And therefore dare their pow’r defy,
Assured of conquest through his name:
But soon my confidence is slain,
And all my fears return again.
Thus different pow’rs within me strive,
And grace, and sin, by turns prevail;
I grieve, rejoice, decline, revive,
And vict’ry hangs in doubtful scale:
But Jesus has his promise passed,
That grace shall overcome at last.
This hymn (sung to the tune “Solid Rock”) is found on pages 450-451 of The Works of John Newton, Volume 3.
