Some timeless words from Charles Haddon Spurgeon:
Our faith is a person; the gospel that we have to preach is a person; and go wherever we may, we have something solid and tangible to preach, for our gospel is a person. If you had asked the twelve Apostles in their day, ‘What do you believe in?’ they would not have stopped to go round about with a long sermon, but they would have pointed to their Master and they would have said, ‘We believe him.’ ‘But what are your doctrines?’ ‘There they stand incarnate.’ ‘But what is your practice?’ ‘There stands our practice. He is our example.’ ‘What then do you believe?’ Hear the glorious answer of the Apostle Paul, ‘We preach Christ crucified.’ Our creed, our body of divinity, our whole theology is summed up in the person of Christ Jesus.
