Not really; it's like having children. It's %100 due to the Seed, and %100 due to the Egg. The issue you have is because you reject Compatibalism; but you shouldn't. Having children isn't due to 50-50, but is due to two distinct %100's...You are contradicting yourself
Stating salvation has no conditions
and salvation has a condition
%100 x %100 = 1...
