If you haven't heard of the book Beside Still Waters, I would recommend it to you. It's a collection of sermon excerpts from Charles Haddon Spurgeon, specifically on comfort for believers in Christ. We named our firstborn, Haddon, after this pastor.
Below is my favorite sermon from this book:
I Know Their Sorrows (Exodus 3:7)
"If you are in the dark, if your spirits are sunk in gloom, do not despair, for the Lord Jesus was there. If you have fallen into misery, do not give up, because the Father's well-beloved passed through denser darkness. Believing soul, if you are in the dark you are in the Kings cellars, where the well refined wines on the lees are stored (Isaiah 25:6). You are in the Lord's pavilion, and you may speak with Him.
Yes Lord, in hours of gloom,
When shadows fill my room
When pain breathes forth it's groans
Then thou art near.
If you are under a cloud, seek your Lord,. Stand still in your deep sorrow and say, 'Dear Lord, the preacher tells me that your cross once stood in darkness like this. Oh, Jesus, hear me!'
He will respond. The Lord will look out of the pillar of cloud and shed a light on you. He is no stranger to heartbreak. 'I know their sorrows,' said the Lord to Moses (Exodus 3:7). Trust him, and he will cause his light to shine on you. Lean on Him, and he will bring you out of the gloomy wilderness and into the land of rest. May God help you lean on Him."
I still cling to the truth that Jesus has passed through denser darkness, and that I am in his cellars on days of sorrow. In sadness we get to know the man of sorrows (Jesus), in a way that we can't when all is going well.
"He was despised and rejected by men;
a man of sorrows, and acquainted with grief..."
