Most people think that the apostles immediately became the temple of the Holy Spirit after the cross. They didn’t. They became baptised with the Spirit at Pentecost.

They are also many think the apostles knew the Law was obsolete from Acts 1. No they only got that idea in Acts 15. 10 years after resurrection.

Hence I can’t understand why believers can’t accept the fact that not all believers were made the new temple of God until 40 years after the cross.

The bible speaks about the gathering of the 144,000 and the multitudes. It speaks about the destruction of the 1st temple before the coming of the new one.

Hebrews 9:8
By this the Holy Spirit indicates that the way into the holy places is not yet opened as long as the first section is still standing.

The new spiritual Israel was being formed. It took them 40 years for an old generation to phase out and a new one to come in.
