Best is opinion. If you want a complete deck list, I believe there are various versions posted online.
Personally I prefer to build the deck myself so if you're like that and just wanting a starting point then I'd say:
TGT, TGT characters which usually is the 4 white girls and John. Add Susanna and a few more disciples like James, Thad, Philip, Bart. Then include the obvious battlewinners like AoC, My Lord My God, He is Risen.
That gives you a start to build on. Then I think it depends if you want a balanced deck or almost all offence. 10 heros is enough for a more balanced deck. You also want to choose if you're going to focus on speed (Peter, 4DC, Reach, Words, Pentecost, First Fruits), lost soul generation, territory destruction to help ignore, more battlewinners, recursion, etc.
People talk like there is only one way to build these decks and they are all cookie cutter but thats not how I approach it. Of course there is going to be overlap but I see a lot of good choices available. The Nats winning deck included Red which was not the norm and I've built a variation that included the Samaritans also.
