Dr. Radmacher used to pray that he would get saved whenever he got up to preach. I pray that I get saved while writing this blog post. I hope that you get saved when you read it. And no, I am not talking about eternal life in any of those sentences.
We receive eternal life, not be believing the entire gospel (this is impossible anyway), but by believing in Jesus for eternal life. Though one does not need to believe the entire gospel to receive eternal life (and nobody can believe all of it anyway), one of the central truths at the heart of the gospel which must be believed is the truth about God’s absolutely free offer of eternal life through Jesus Christ.
Some Calvinists say that Calvinism is the gospel. I say that Jesus is the gospel. There are no four laws, five points, or six steps to the gospel. There is only Jesus. When a person is presenting “the gospel” they obviously cannot share everything, and so they do their best (along with the help of the Holy Spirit) to pick and choose which truths of the gospel should be shared in that particular context to those particular people.
