Profound thought. I think it is easy to get caught up in the average understanding. But I think really that that average thought is really only the gospel message. Don’t get me wrong, the gospel is the immediate need and very important! However, as Platt assesses, there is more to biblical Christianity than just the gospel. It is a Christian’s duty to spill over and give generously all that God has given him/her. So because God loves a Christian, the Christian should love others as he/she loves him/herself. Because God cleans a Christian of his/her sins, His cleansing makes it possible for the Christian to do good. Therefore, God shared it, a Christian should share it (in a way that is loving). God is great and amazingly glorious and has shown it to the Christian. A Christian should tell others of this amazing God.
I would say that ‘The message of Christianity is that God loves me enough to send his Son, Jesus, to die for me.’ is the gospel message, and God loves me so that I might make him–his ways, his salvation, his glory, and his greatness–known among all nations.” is the biblical message that incorporates the gospel.
