I think one of the most awesome things I have found in this brief description of Jesus’ first ministerial trip to Jerusalem is that we can clearly see that Jesus knew His purpose from the beginning.
No man had to show Him how to be the Son of God nor did He have to learn how to become the Redeemer!
John shows us a brief but explosive testimony that Jesus gave of Himself. He knew that His Father was God. He knew that He came to die. He knew that He would be resurrected three days later. And He knew the hearts and motive of everyone He met.
Jesus may have hid His identity at other times in His ministry but His first entrance was a big one!
Behold, I will send my messenger, and he shall prepare the way before me: and the Lord, whom ye seek, shall suddenly come to his temple, even the messenger of the covenant, whom ye delight in: behold, he shall come, saith the Lord of hosts. But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner’s fire, and like fullers’ soap: and he shall sit as a refiner and purifier of silver: and he shall purify the sons of Levi, and purge them as gold and silver, that they may offer unto the Lord an offering in righteousness. Then shall the offering of Judah and Jerusalem be pleasant unto the Lord, as in the days of old, and as in former years. And I will come near to you to judgment; and I will be a swift witness against the sorcerers, and against the adulterers, and against false swearers, and against those that oppress the hireling in his wages, the widow, and the fatherless, and that turn aside the stranger from his right, and fear not me, saith the Lord of hosts. For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.Malachi 3:1-6
He came in power against sin. Moreover, He came in the power of amazing grace so that we are not consumed by His rage against sin but made able to stand by the power of his grace and mercy.
