THE HOLY SPIRIT CONFIRMS
On the Day of Pentecost and following it many Jews became convinced that Jesus of Nazareth was their 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, they might seem to make the Old Testament irrelevant. Inspired by the Holy Spirit the writer reveals, compares and contrasts the Old Covenant with the New Covenant.
So, does that mean the Old Testament is redundant? Of course not. Then how should the Lord's New Covenant Kingdom people read it?
