The heart of the gospel is redemption, and the essence of redemption is the substitutionary sacrifice of Christ. They who preach this truth preach the gospel in whatever else they may be mistaken; but they who preach not the atonement, whatever else they declare, have missed the soul and substance of the divine message.
Charles SpurgeonI believe certain doctrines because God says they are true; and the only authority I have for their truth is the Word of God. I receive such and such doctrines, not because I can prove them to be compatible with reason, not because my judgment accepts them, but because God says they are true. Now this is one of the best services we can render to God,-to submit ourselves to him in our belief of what he has revealed, and ask him to fix his truths in our hearts, and make us obey them.
Charles Spurgeon
