Very early in my walk in the Lord, I came across this quote by Charles Spurgeon which had a profound effect on my evangelism and preaching.
“I do not look for any other means of converting men beyond the simple preaching of the gospel and the opening of men’s ears to hear it. The moment the Church of God shall despise the pulpit, God will despise her. It has been through the ministry that the Lord has always been pleased to revive and bless His Churches.”
