I believe spiritual gifts exist today. So no, no contradiction at all (for me).That would mean the bible contradicts itself which it does not..understand that Paul was referring to spiritual gifts which do not exist today!
I know the argument that sign gifts have ceased (that their function as a "sign" is no longer relevant). I am not sure what passages you believe indicate that spiritual gifts are not given, but you are right that that idea is contradicted by Paul (particularly when he lists love not only as a spiritual gift but as one that is eternal). Why do you believe that spiritual gifts do not exist today and what passages do you offer in support (which ones do you believe are contradicted by the existence of spiritual gifts today)?
