THE HOLY SPIRIT CONFIRMS
From the Day of Pentecost on many Jews became convinced that Jesus of Nazareth is their prophesied Messiah. And they received Him. But, as time went by, they needed special guidance and assurance about hearing the word of Christ because of their Old Testament orientation.
God met their need. He inspired a special letter to explain these things to them, and to all who received Christ after them.
Right at the start of the letter the Holy Spirit confirms what the Father had spoken to the three Disciples on that mountain, with these words:
"God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, Hebrews 1'1-2.
God spoke in time past to the fathers - by the prophets.
In these last days He speaks to us - by His Son.
These are history-making words indeed. However, on the surface, it might seem to make the Old Testament irrelevant. Nevertheless, the writer reveals, compares and contrasts the Old Covenant with the New Covenant as he is inspired by the Holy Spirit.
So how should Christ's New Covenant Kingdom Believers regard the Old Testament? What is the relationship between them?
