In the beginning was the Word, and the Word was with God, and the Word was God (Joh 1:1).
God’s counsel and purpose for man was fulfilled in Christ. Jesus is the word of God;He is the one of whom God spoke in the law and prophets. He Himself testified of this: “Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me” (John 5:39).
The prophecies about the Messiah to come were detailed in scripture that when Herod sought to kill Jesus at His birth, and he inquired where Jesus was born, and they replied accurately. “And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet” (Matthew 2:5). The nature of His birth, His life on earth, and His redemptive work were all foretold. In fact, the book of Matthew is a compendium of prophecies fulfilled in Christ Jesus. See Matthew 1:21-23; 2:13-15; 2:16-18; 2:23 to mention a few.
In a remarkable ‘bible study’ Jesus had after His resurrection, the bible says: “And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself” (Luke 24:27). So, you can teach about Jesus from the Old Testament. He is not ‘a subject,’ He is ‘the subject.’ The scriptures are meant to be about Him.
Our teachings today shouldn’t be any different. They must be Christ-centered. If our teachings do not help people understand who Christ is and what He has done, we have wasted our time.
