I love this opening line of Charles Spurgeon’s sermon on Song of Solomon 1:4, The memory of Christ’s love:

Charles Spurgeon
I Do not think I can preach tonight. I feel so weary, and worn, and ill. Still, I can talk to you a little concerning the great love of Christ. If I were dying, I think I could speak upon that theme, and oh, when we rise again, how we shall talk forever and ever about Christ’s love! This will be our endless theme throughout the eternal ages, “His great love wherewith He loved us, even when we were dead in sins.”
Though Spurgeon was tired, sick and burned out, he could still rave about the love of God in Christ Jesus. Oh that I might be close enough to Christ that his love overflows even in my weakness and weariness.
