Because the word says that God no longer winks at ignorance but commands all men everywhere to repent. BTW, I'm with you on the restoration thing. Jesus said the gates of help shall not prevail against the church. It never needed to be restored, its always been here. And who said 100 % accurate? Not me.<quoted text>
If one must be 100% right in doctrine and practice before they are saved, then when is the exact date when we reached that restoration stage? Was it in 1860? 1890? 1930? 1950? 2010? When?
What if we have been wrong on a number of things and because of our misunderstanding have taught and practiced error for several generations? What if we have been wrong about the subject of grace during all those past generations? Will grace cover us, as it covered the misunderstandings of the Jerusalem church for a generation?
Is it okay to have some error after we are saved but none at all before we are saved? I contend if one be baptized, no matter what he understands, he is my brother. He has done as God ask. If God will overlook ignorance after we have been saved, why will he not before we are saved?
By the way, the Jerusalem church did not have the completed revelation about the gentiles until after the events of Cornelius. After that, the issue of circumcision came up before the Jerusalem council. Yes, some did believe that circumcision was necessary before the council. But how about after? Do you think that the doctrine they held was to be tolerated afterward? Could they still personally teach circumcision and law keeping as necessary for salvation, and be in good standing with God after they received that knowledge?
You seem to be saying that God will accept our baptism no matter what we believe about it. Maybe we really should be baptismal regenerationists then. If it doesn't matter WHAT we believe, it then doesn't matter IF we believe.
