I like what I read about feelings in a book of writings by Charles Spurgeon. Here is an excerpt:
"Often do we hear the lamentation - 'I do not feel that I can be saved. I do not feel that I am forgiven. I do not feel it is possible my hard heart can ever be softened and renewed.'
This is poor, foolish talk. In what way can our feelings guide us in such matters? Do you feel that the dead can be raised again? Do you feel that the cold of winter will be followed by the heat of summer? How can you feel these things? You believe them. To talk of feeling in the matter is absurd.
I am the subject of very changeful feelings; but I have learned to set small store by them, either one way or the other. Above all, I have ceased to estimate the truth of God's promise by my condition of mind."
Today I feel so joyful that I could dance, but perhaps when I wake tomorrow morning I shall only be able to sigh in harmony with Jeremiah's lamentations. Has my salvation changed according to these feelings? If so, it must have a very movable foundation.
We are saved according to facts, not fancies. Certain eternal truths prove us saved or lost; and those truths are not affected by our happiness or depressions."
