What was Israel's prospect after Jesus left?
The nation's prospect was that at Pentecost, the gathered nation of Israel would receive the Holy Spirit's power and be baptized into it, enabling them to continue the miracles, signs, and wonders Jesus had performed for three years. They would literally carry on as believing Jews what Christ had done.
Les explains that at Pentecost, a Jewish feast day, the nation of Israel was gathered, and the Holy Spirit came with power. This was the Jews' valid offer again to experience that power of the Holy Spirit to do miracles, signs, and wonders, as Jesus had done. So this was the nation's prospect: they could literally carry on as individual, believing Jews what Christ had been doing for three years. How would He manifest it? By placing them into the very power of the Holy Spirit. As chapter 1, verse 8 says, 'you shall receive power.' The whole concept was that Jesus would be the baptizer, and Israel would be the baptized.
