Spike,
I don't see an issue with Us disagreeing on the interpretation of Romans 10:13, to me its not a case of right and worng, but a discussion that hopefully brings people closer to God.
To me its not about it being Jesus or God because I don't choose between them, it's not a case og either/or for me, its a case of Both in union.
God is our Father and His Son Jesus is our Lord and saviour, redeemer and judge THROUGH the father, Jesus is the new convenant because the Father made it so, and all the Jesus is, the father is, for all the Jesus is, is throught the father NOT instead of.
