That is INCOMPREHENSIBLE, illogical, unreasonable, and makes no sense!
But that is what the Bible says that God does: He gives us the free gift of salvation based on his love for us ...alone.
Salvation occurs by only one means: the power of God's declaration of righteousness/the power of his Word. "Faith comes by hearing and hearing by the Word of God."
In the New Testament, God says that he uses his Word to save and forgive sins in two situations: when the Word is preached, and when the Word is spoken with the application of water…Baptism.
It's that simple.
Who do Lutherans baptize? Answer: We baptize anyone who comes to us, or is brought to us, seeking God's free gift of salvation and the forgiveness of sins. Do you have to be baptized to be saved? No. But why would you refuse this beautiful act of God? Why would you refuse God's gift of the forgiveness of your sins?
If you neglect, reject or despise this command of Christ, do you really have true faith?
As Christ says in Mark 16:16, it is not the lack of baptism that damns, it is the lack of belief/the lack of true faith that damns.
