We give unbelievers what's called the Roman's Road to Salvation.
Not I. Though I fully believe that St. Paul's Epistle to the Romans is, arguably, some of the best articulated theology and provides a very good and thorough treatment of Law and Gospel.
On the Internet however, unbelievers ask deep theological questions.
That was kinda cheap, wasn't it, Lutheran?
It wasn't intended to be a low blow. It's a critique of the fact that you don't actually preach Jesus Christ, Him crucified and risen from the dead, and the Gospel of our salvation in Him. Instead, you preach KJV-onlyism and a rejection of science.
Let's see you answer half the questions I get.
What's your version of the Great Commission?
I don't have a version of the Great Commission, it's just what Jesus Himself instructed of His Apostles and Church: To preach the Gospel, make disciples, to administer Christian baptism, and to instruct and teach.
So the Church has done just that: A preaching of the Gospel and the administering of the Sacraments, and teaching, instructing--and through these means the Holy Spirit works and accomplishes His work: Regeneration, justification, sanctification, et al.
But in order to preach the Gospel it's important to actually preach the Gospel, and not preach something else that isn't the Gospel.
"Become a Christian or burn in hell" is not the Gospel.
The Gospel is good news. If what you're preaching isn't GOOD news then it can't be called "gospel". And in order for it to be called the GOOD news of JESUS CHRIST, it has to be about who Jesus is and what Jesus has done, and what we receive and have in Jesus and from Jesus. Thus the Gospel is preached for faith, as St. Paul says in Romans 10:17, "faith comes by hearing and hearing by the word of Christ"; as faith comes not from ourselves, but from outside of ourselves--from God, as the gift and work of God; as St. Paul says in Ephesians 2:8-9, "For it is by grace that you have been saved, through faith, and this is not of yourselves, it is the gift of God, not of works so that no one may boast."
The word which is from God in Christ, the Gospel, for sinners; that the sinner might hear of the work and gift of God which is in Christ for sinners: forgiveness, a clean conscience before God, righteousness from God, peace with God through these things in Jesus; and the promise of eternal life, even the very resurrection of the dead when in the end God brings all things to completion, renews all things, and sets all things to rights.
The good news is not that we are all going to hell unless we sign on the dotted line on some contract from God, as though we have to make some kind of transaction with the Almighty in order to avoid eternal punishment. That's not the Gospel, that's extortion.
God is not the one who holds men hostage and demands ransom.
