From Mere Christianity by C. S. Lewis:

“But the great thing to remember is that, though our feelings come and go, His love for us does not. It is not wearied by our sins, or our indifference; and, therefore, it is quite relentless in its determination that we shall be cured of those sins, at whatever cost to us, at whatever cost to Him.”

I came across this encouraging quote while reading and thought you might appreciate it.
