Were the Apostles converted before the Holy Spirit came at Pentecost?

Summary

The main theme is the nature of true belief and regeneration, particularly as exemplified by Jesus's interactions with his disciples in John 13 and John 15. The sermon references Jesus's washing of his disciples' feet and the imagery of the vine and branches to illustrate this. The practical takeaway is that while outward professions and specific conversion narratives are common, true regeneration is ultimately known by God and can manifest in diverse ways, even before the full coming of the Holy Spirit.
