Why then would it require Jesus Christ more than an instant to impart into Paul what he wanted him to do?
I will answer you using something my parish priest once said. The Divine Liturgy in the Orthodox Church contains parts that are not always sung because they don't apply. Thus, there are prayers for the dead which are included on specific occasions but are normally not included. There are prayers for the catechumens (people being brought into the Church who have not yet been baptize and/or chrismated). My priest always includes those prayers, yet I know we don't have any catechumens at this point.
I asked him "why do you include the prayers for the catechumens?" and he said "Because I know I believe. I don't know if anyone else does."
With God all things are possible, but everyone says that they are guided by the Holy Spirit. I don't know that. Not all could be because the Spirit would not lead people apart.
God does not think like we do. Why suppose that everyone must submit to the domination of one sect?
