Pedal, their preaching of the Kingdom is almost wholly false. In fact, the JW message regarding the Kingdom is so deeply wrong that it alone would DISQUALIFY them from being approved by God.
Your understanding of the reality of the Good News of the Kingdom versus the false Good News the JW's preach needs some investigation.
What do the JW's preach?
That Christians will live on a paradise earth, not go to heaven. FALSE. The only hope offered for Christians in the Scriptures - EVER - is Heaven. There may be a Paradise Earth, but NOT for Christians. So, JW's preach a false good news, a false gospel, one totally different to what Jesus and the 1st century Christians preached.
They preach that Jesus became King of this Kingdom in 1914. FALSE (I think you know this). They also preached as 'God's promise' that many of those alive in 1914 would DEFINITELY be alive when Armageddon came. FALSE.
You don't get points from God for preaching a false good news. You get condemned. The Scriptures are clear on this. Or can you tell me what you think is accurate about what the JW's preach about the 'Good News'?
