Peter Pett's Commentary on the Bible
Matthew 3:11
“I indeed baptise you in water to repentance, but he who comes after (or ‘behind') me is mightier than I, whose shoes I am not worthy to bear. He will baptise you in the Holy Spirit and fire,”
John has ever before his eyes the One Who is coming. That is why he is baptising in water. His baptism is as an acted out prophecy of what is coming, and in order to prepare men for it. It is a picture of the fact that the One Who is coming will fulfil the promises of the prophets and drench them with the Holy Spirit and fire. He, John, is preparing them for it, but he wants them to be aware of the fact that one day soon the greater reality will come. See Isaiah 32:15; Isaiah 44:1; Joel 2:28; Ezekiel 36:25; Malachi 3:1; Isaiah 4:4; Zechariah 13:9.
‘He who comes after (opisow) me.' ‘After' (opisow) is not usually a time word (never elsewhere in Matthew, see Matthew 4:19; Matthew 10:38; Matthew 16:24), although instances are known. The thought may therefore be that John knows that the Coming One will become his follower (come after him), but will in the end prove to be high above him. Alternately we may see it as a rare use of it as meaning ‘after' in time.
‘I indeed (ego men).' This is a typical Matthaean emphasis bringing out a contrast. Here it signifies ‘I in contrast with Him'.
“I indeed baptise you in water to repentance.” He recognises that his baptism is the lesser work of God, a prophetic acting out of a greater reality yet to come. ‘To repentance' is probably better rendered ‘because of repentance'. It was not inducing repentance but accepting that it had taken place, as the very coming of the people to him, and their open admission of sins, revealed. But that was all that John could do. While God could change their inner hearts, there was nothing that he himself could do about it except preach and then leave it to God. How different it would be in the case of the One Who was coming Who had the power within Himself to give life (John 5:21), and Who could drench men in the Holy Spirit.
‘He is mightier than I.' The Coming One would be the Reality to which John was the shadow. John wants all to know that although he himself may be a prophet, and powerful through God, he is but in the end an ordinary man. But this One Who is coming is God's ‘Superman', with a power that will be far greater than his. He is the mightier than John. Indeed, as we learn later, while Satan can be thought of as a ‘strong man' (Matthew 12:29) Jesus is ‘the stronger than he' (Luke 11:22), a fact which will shortly be demonstrated by Jesus in the same wilderness (Matthew 4:1). Thus His mightiness is here first revealed by John in order for it to be demonstrated by His resistance to the wiles of the Devil. He will be all-powerful and all-prevailing. We could add with Isaiah, ‘He will be the Mighty God' (Isaiah 9:6). But how far John was aware of the full implications of this we do not know.
For we should note that it is possible to be aware of the divinity of Jesus without being able to put it into words. The inner sense is there even when it cannot be verbalised. Indeed throughout the ages no one has been able to put it into words in a full satisfactory way, for human language does not have the means to do so. Many who have been heretics in their words have been orthodox in their hearts. Many an Arian died willingly for Christ out of love for Him, and not all have the refined ability of the advanced theologian. And many church members today are heretics without knowing it because of what they would say that they believed about Jesus as the Son of God, although their hearts would say otherwise, because their belief has never been tested out or corrected. But fortunately God looks at the heart and understands the problem. He knows how difficult it is for us to grasp the full significance of His tri-unity.
And John sees Him as not only greater than he but as holier as well, for John sees himself as not fit even to take off and carry His shoes (the carrying of the shoes assumes that they have either just been taken off or are about to be put on, so that it also indicates the taking off of the shoes). Dealing with a man's shoes in this way was the task of the lowest slave, (the Rabbis declared that even a Teacher in those days would not expect his disciples, who would perform most general tasks for him, to perform a task like this for him), and thus by these words John is humbling himself into the very dust. He is declaring that he is not even fit to be the Coming One's humblest slave. So the Coming One will be mighty and holy. In the words of Isaiah He will be the Mighty God, the Everlasting Father, the Prince of Peace, the One Who is powerful, compassionate and merciful (Isaiah 9:7). Note how these two aspects described by John, His mightiness and His holiness, will be brought out in the parallel where the voice from Heaven will declare Him to be God's beloved Son, and the One Who is totally pleasing to God (Matthew 3:17).
But as we shall later see, while John was right in what he said about Him, he was not fully right in his own interpretation of it. He saw the Coming One as the One Who would come like a powerful wind, a wind of the Lord driving a rushing river (Isaiah 59:19), a powerful tempest toppling trees before Him, a sweeper away and burner of chaff. He was a little short on what stamped Jesus off as unique, His love, and compassion, and mercy; His gentleness and tenderness. As Jesus would later have to point out to an anxious John, lying puzzled in his stinking and dark prison, while it was true that He had come like ‘a rushing wind', it was first of all as a wind of healing and of hope as Isaiah had also prophesied, dealing gently with the bruised reeds and fanning the dying embers of the flax into flame, rather than dousing them in His fury (Matthew 11:1 to Matthew 12:21).
‘He will baptise (drench, overwhelm) you in the Holy Spirit and fire,” John's baptism pictured this forthcoming climax. He would come like deluging, life-giving rain, and purifying and consuming fire. On those who were ready to receive Him He would come like the life-giving rain, the Holy Breath, in the ‘washing of regeneration and renewing of the Holy Spirit' (Titus 3:5). He would produce fruitfulness and blessing as the prophets had made clear (Isaiah 44:1; Ezekiel 34:26; Ezekiel 36:25; Ezekiel 37:1; Ezekiel 37:14; Jeremiah 31:27; Psalms 72:6; Zechariah 10:1). And He would come like refining fire (Malachi 3:1; Zechariah 13:9). Purity, holiness and goodness would abound. But the same fire that would refine would also burn up what was only chaff (Isaiah 5:24; Isaiah 66:16; Isaiah 66:24; Ezekiel 15:6; Ezekiel 22:21). His fire would not only purify, but would also destroy. The message is one of sharp division. To those who believe, life and blessing, refreshing rain and a purifying wind, and along with it the purifying fire, but to those who do not believe He would be a scattering tempest and a fire of destruction.
