historian said:
Jesus is still on our midst. The difference is that His presence is not physical. It's spiritual. He promised to be with us until the end of the age.
No. When Jesus is physically here, that is when the Kingdom of Heaven is in your midst. When Jesus returns physically back to the Earth then the kingdom of heaven will be in our midst again. Jesus is going to set up a physical kingdom here on Earth when He returns. Yes the Holy Spirit is here to teach us and guide us until that happens but that is not the kingdom of heaven. That is why Paul didn't preach the kingdom of heaven.
