The good news of the person and work of Jesus Christ Who He is and what He did in His work. How sins are atoned for and forgiven and how we are made right with God.The coming of the kingdom of God. Matthew 4:17 “From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand”
Warning: Reject the gospel and go on sinning willfully after receiving the knowledge of gospel truth then what you should expect is a terrifying judgement. Hebrews 10:25-25 “For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.”
Matthew 11:15 “He who has ears to hear, let him hear.” This is a call to listen. This is a call to be alert.
