What is the gospel is?

The gospel of the New Testament is the same good news of God which was promised in Old Testament Scriptures. Jesus Christ is the subject and the Author of the gospel, but gospel began long before the birth of Jesus. The gospel began long ago in the mind and plan of God, and God foretold the coming of the gospel i.e. His Son through the prophets of old.

Mark 1:1-3

1 The beginning of the gospel of Jesus Christ, the Son of God. 2 As it is written in the Prophets:
   “Behold, I send My messenger before Your face,
 Who will prepare Your way before You.”
3 “The voice of one crying in the wilderness:
 ‘Prepare the way of the Lord;
 Make His paths straight.’ ”

John 5:39

39 You search the Scriptures, for in them you think you have eternal life; and these are they which testify of Me.

Acts 26:22

22 Therefore, having obtained help from God, to this day I stand, witnessing both to small and great, saying no other things than those which the prophets and Moses said would come—

Hebrews 1:1

1 God, who at various times and in various ways spoke in time past to the fathers by the prophets,

2 Peter 1:20-21

20 knowing this first, that no prophecy of Scripture is of any private interpretation, 21 for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.
