The True Gospel
If you tell people that Jesus loves them and you love them, and if you show them kindness, that is good, except it is evil if it's all you tell them of Jesus. Never dare tell the people of the World that Jesus loves them without also telling them that His love took the form of dying for our sins as our substitution in God's judgment in full accordance with the prophecies of it beforehand and the descriptions of it given afterward in the Bible, and then He was buried, and then God raised Him from the dead on the third day in accordance with the Bible, and then He was seen afterward by Peter, the Disciples, over 500 brothers at once (most of whom were still alive when Paul spread to the Corinthian congregation this formulation of the gospel that he had also been taught, but some of them had passed away by then), and then Jesus was seen after His Resurrection by James, and the Apostles at large and then by Paul, and that believing these things we must call on the name of the Master to be saved by verbally confessing Master Jesus, and that we must continue to believe these things until our journey here is over. Anything other than this good news is another gospel, which we have been strictly warned against in the Bible.
Merely telling people that Jesus loves them is technically true, but it obscures HOW Jesus loves us - by dying as a sinner (although He never committed sin) in our place to justify all who believe these things and who confess Master Jesus for our salvation. Then, our belief in the Resurrection will also lead us away from our old sin-filled actions to right actions, as we are led now not by written Law like Moses was bound but by the Law of the Spirit of Life in Christ Jesus! He makes all His own new creatures!
Not Liberalism or Gnosticism or Social Gospel or Hinduism or any other Philosophy or Religion will ever bring a fallen sinner to right relationship with God through Christ. Only by HIS WAY, as preached by His great Apostle Paul, will anyone be saved.
