1.  Lord Jesus’ temptation was preceded by His introduction as the Lamb of God, baptism, new infilling  with the Holy Spirit and approval as the Beloved Son of God.
I’m writing today about the the prelude to Satan’s temptation of Jesus in the wildernessOne of the outstanding truths is that  Lord Jesus’ temptation was preceded by His introduction as the Lamb of God, baptism, new infilling  with the Holy Spirit and approval as the Beloved Son of God.  
Apostles Matthew, Mark and Luke wrote that Lord Jesus was baptized by John the Baptist prior to his temptation in the wilderness. John the Baptist had warned the Jews to prepare for the arrival of the Messiah. His message was also one of  repentance and many were baptized under his ministry.
a. John the Baptist introduced Jesus as the Lamb of God
Jesus also came to be baptized.  As Jesus approached the baptism scene, John the Baptist prophetically declared that He was the Lamb of God and also did so the following day (John 1: 29 – 36).  John really did not see the need for Jesus to be baptized, but the Lord told him that it was necessary in order “to fulfill all righteousness”  (Matthew 3: 14 & 15).
This declaration that Jesus was the Lamb of God marked the fulfillment of Isaiah’s  prophecy (chapter 53). However, the people, being spiritually blind, did not understand the meaning of John’s words.
b. How did John the Baptist know that Jesus was truly the Messiah?
John was sent to earth to be the Announcer of the Messiah. This was a very important mission. Why was he so accurate? He confessed that he had no way of knowing the identity of the Messiah apart from two signs given by the Father:
a. The Messiah would come to be baptized
b. The Holy Spirit would descend and remain upon Him (John 1: 29 – 34).

I hear the Father say that John’s experience is a testimony to those seeking confirmation for key decisions

c. Jesus’ baptism and new infilling  with the Holy Spirit
Jesus was baptized (baptizō/G 907) by John. The root word baptō (G911) indicates that He was DIPPED into the water, not just sprinkled with it (Luke 16: 24, John 13: 26, Revelation 19: 13).
The Apostles documented that Jesus had a vision as He came up out of the water. He saw the heavens opened and the Spirit of God descending on Him like a dove, filling Him again and preparing Him for this new dimension of ministry (Matthew 3: 16; Mark 1: 10; Luke 3: 31 & 32a; John 1: 29 – 34).  John the Baptist also saw  the heavenly vision  (John 1: 29 – 34). The message is that God establishes truth in the mouth of two or more witnesses.
Jesus had been filled with the Holy Spirit from His conception (Luke 1: 35), but this new infilling was necessary for the nature of the ministry He was about to fulfill.
d. Father confirmed verbally that Jesus was the Beloved Son of God
There was ONE final miraculous manifestation at the baptismal scene as John the forerunner introduced Jesus as the Messiah to the nation of Israel. Both the Lord Jesus and John heard a voice from heaven saying, “this is my beloved Son, in whom I am well pleased” (Matthew 3: 17; Mark 1: 11; Luke 3: 22).
The scene of Jesus’ baptism was one that marked a spiritual euphoria in a sense. Next thing you know, the Apostles said that Jesus was sent, driven to the wilderness for a period of temptation by the devil:
Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil – Matthew 4: 1.
And immediately the Spirit driveth him into the wilderness – Mark 1: 12.  

 And Jesus being full of the Holy Ghost returned from Jordan, and was led by the Spirit into the wilderness – Luke 4: 1.
