Jesus Christ, eternal, coming to earth fully as man and God, being the Messiah prophesied in the Old Testament, sits now at the right hand of the Father as our intercessor.
The "Good News" that we proclaim was perfectly put to words by the Apostle Paul in his letter to the Corinthian church in which he says "that Christ died for our sins in accordance with the Scriptures, that He was buried, that He was raised on the third day in accordance with the Scriptures".
God's special revelation to man, written through man, breathed out by God, of which the Scriptures say it is "profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be complete, equipped for every good work".
