12 In all sincerity I tell you: the one believing in Me and the works that I do, he will do even greater things than these, because I am going to the Father.
13 And I will do whatever you should ask in My name, so that the Father may be glorified through the Son.
14 I will do whatever you ask Me in My name.
A person who has to make a statement in a court of law has either to take an oath to do so, or to make a solemn promise that they will tell the truth. The truth is very important to us, both in receiving what someone says, and also in what we say. There are other times when we want to assure others that we are telling the truth, even if we are known for our truthfulness and integrity.
Jesus was certainly known by the disciples as always telling the truth. Yet in that Upper Room Jesus felt that it was necessary for Him to assure His disciples that He was very sincere about what He was saying, and His sincerity was His truthfulness.
Therefore, what Jesus was about to say came from the same that had just said: “I am the Way, The Truth, and the Life”.
He was telling His disciples, and therefore, us, that there was no doubting the truth and validity of the promise He was about to make.
As we look at these promises we need to let the Holy Spirit root them deep within the soil of our souls.
In these verses are contained two great promises that Jesus made.
The first is: whoever believes in Jesus will do the same works that He did.
The second promise is: those who believe in Him will do even greater things than what Jesus did. These are tremendous promises that bring great potential for every believer.
What did Jesus mean when He said that ‘whoever’ believes in Him.
To have faith in Jesus means to be fully and totally and absolutely persuaded about who Jesus is. He had just been telling His disciples that He is in the Father and the Father is in Him. In this He was sharing with them the reality of the uniqueness of His relationship with the Father.
This is the context of the belief that Jesus said is necessary for all who come to Him, and it is this belief that sets the context for these two promises. The key to moving into the reality of these two promises is being persuaded about the oneness of the Father, the Son, and the Holy Spirit.
