Jesus was referring to the physical temple in Jerusalem, when He quoted the prophet Isaiah, 'My house shall be called a house of prayer for all nations'. As our Lord predicted, that physical temple in Jerusalem was destroyed in the year seventy AD. When Jesus was crucified on the cross, the veil in that temple was torn in two, and God no longer dwells in a temple made with human hands. Under the new covenant, all believers in Christ have now become the temple of the living God. In the current church age, the temple of God on earth has changed, but the purpose of that temple has not. All believers are now the house of God, and as such, we are called by God to be His house of prayer for all nations. This book looks at how we are to fulfil our call to prayer.
