Only one person has the power to convert any human being to Christianity.
That person is God the Father.
Even Jesus Christ Himself lacks that power because it would be a self-glorification.
This doctrine is elaborated in the doctrines of Common Grace and Efficacious Grace.
The Great Commission, Matt 28:16-20, does command believers to teach all nations, baptizing them in the name of the Father, the Son, and of the Holy Ghost.
Human beings do not have the ability to create human spirits. If they did, then they would also be accountable for leaving some people without salvation.
“Only one person has the power to convert any human being to Christianity. That person is God the Father.”
Holy Spirit does it all the time.
“Even Jesus Christ Himself lacks that power because it would be a self-glorification.”
God is VERY MUCH INTO self-glorification. Everything He does is for His own glory. He uses Jesus for that all the time. http://www.desiringgod.org/articles/why-it-matters-that-god-does-everything-for-his-own-glory
When Saul was blinded on the road to Damascus it was the voice of Jesus that he heard and not the voice of the Father or the Holy Spirit. Jesus converted Saul to Christianity in that moment.
Agreed.
