Why do we preach the gospel?

I was preaching, quite recently, on the theme "why do we preach the gospel". Part of the message asked the question "What is the gospel?" from 1 Cor 15v1-4. The second section dealt directly with the question "Why do we preach the gospel?". Here are the ten reasons I gave. They have been challenging me a lot in thinking of how I live with others and communicate the gospel to them, and if I really consider what is at stake or not or if I strive to talk with them about Jesus!

1. Because Jesus commanded us to (Mark 16v15). As it is a command we will give an account as to our response (2 Cor 5v10).

2. Because it's God's chosen means (1 Cor 1v21; Rom 10v14, 17). As it is God's chosen means we have been given the ministry of reconciliation (2 Cor 5v11-19).

3. Because it is the only good news (John 14v6).

4. Because God longs for his people to be saved (2 Pet 3v9).

5. Because the judgement and wrath of God will come upon all unbelievers (Zephaniah 1v14-18, John 3v18). Knowing this reality, our response should be to communicate the good news of the gospel (2 Cor 5v11).

6. Because Jesus is coming and after that it will be too late (Matt 24v14).

7. Because the love of Jesus compels us (2 Cor 5v14-15).

8. Because the advantage must be taken now as more difficult days are ahead (2 Tim 4v2-5).

9. Because we represent Christ in His absence (2 Cor 5v20).

10. Because the Lamb is worthy to receive the reward of His sufferings (John 17v1-5).
