“But, dear friends, perseverance is not the lot of the few; it is not left to laborious preachers of the Word, or to consistent Church-officer it is the common lot of every believer in the Church. It must be so for only thus can they prove that they are believers. It must be so, for only by their perseverance can the promise be fulfilled, "He that believeth and is baptized, shall be saved" Mark 16:16. Without perseverance , they cannot be saved; and, as saved they must be, persevere they shall through divine grace.” – Charles Haddon Spurgeon

“On one occasion when [Henry Drummond] was in England, he was invited to speak at a very uppity, snobbish, high class, west end, London club. Upon his arrival he found all of the members present, and everything was arranged for his message. And he began his speech with this very provocative truth, ‘Ladies and Gentlemen, the entrance fee into the Kingdom of Heaven is nothing. However, the annual subscription is everything.’”

(John MacArthur, GTY “James the son of Alphaeus, Labbeus, and Simon the Zealot part 1” 6/11/07 quoting Henry Drummond)
