The final physical appearance of Christ in the Old Testament was in Judges 13:3-23 when he encountered Samson’s parents before Samson was born. He is referred to as “the angel of the Lord” in this chapter. You may ask “Why is he called an angel when we know Jesus is not an angel? He’s the Lord.” Well, you would have to examine what the word angel actually means. Angel not only refers to the spiritual beings who carry out God’s commands, it refers to the office one holds as delivering messages from God. If you read Revelation chapters 2 and 3, the pastors of the seven churches in Asia are called angels based on this second definition. Therefore, it stands to reason that the ultimate angel, or messenger, of the Lord would have to be Jesus. Throughout his ministry Jesus said repeatedly that he was speaking what the Father told him to speak.
Now, getting back to Samson’s parents, Jesus appears to tell Samson’s parents what is required of them to raise Samson. The first clue we have that this is Christ is when Samson’s father, Manoah, asks the angel what his name is. The angel replies that his name is “secret” in Judges 13:18. This word “secret” also means “wonderful”, the adjective version of the noun “Wonderful” used as one of the names of Christ in Isaiah 9:6.
The second clue occurs when Manoah and his wife offer a burnt offering to the Lord after the angel suggests it. As the offering is burning, the angel ascends up to heaven in the flames. This signifies that the offering is acceptable and pleasing. No one except God has the right or authority to consider an offering acceptable, so this angel was undoubtedly Jesus Christ. The final clue is given to us from Manoah who says “we have seen God” after the angel ascends in the flames.
It is clear that all three members of the Trinity played an active role in the affairs of men in both the OT and NT. This proves that the word of God is consistent and not contradictory. We serve a God who is the same yesterday, today, and forever.
