Sometimes we struggle with doubts, darkness, and a resounding silence when we try to pray. Take comfort - it has happened to all the saints through all the ages. St John of the Cross - a monk and poet in the Sixteenth Century - wrote in one of his poetical works about 'the Dark Night of the Soul'.
Times of struggle and doubt seem to be an integral part of our journey towards God and appear to come to all of us at some point as we continue to grow in our spiritual lives. After all, if we didn't have times of doubt then our faith wouldn't actually be faith - it would be certainty - and probably a very unattractive and arrogant certainty at that.
Here are some quotes from other Christians to help if and when you are in that place:
I would rather walk with God in the dark than go alone in the light.
Mary Gardiner Brainard
I believe in the sun even if it isn't shining. I believe in love even when I am alone. I believe in God even when He is silent.
Now faith is the substance of things hoped for, the evidence of things not seen.
Doubt isn't the opposite of faith; it is an element of faith.
Doubt is not a pleasant condition, but certainty is absurd.
May God bless you in light and in darkness.
