John 14:12

“Verily, verily, I say unto you, he that believeth on me, etc.] Having mentioned his miracles as proofs of his deity, he assures his disciples, in order to comfort them under the loss of his bodily presence, that they should do the same, and greater works; for we are not to understand these words of everyone that believes in Christ, of every private believer in him, but only of the apostles, and each of them, that were true believers in him: to whom he says, the works that I do shall he do also; he shall raise the dead, heal all manner of diseases, and cast out devils; things which Christ gave his apostles power to do, when he first gave them a commission to preach the Gospel, and when he…”

“He that believeth on me - This promise had doubtless special reference to the apostles themselves. They were full of grief at his departure, and Jesus, in order to console them, directed them to the great honor which was to be conferred on them, and to the assurance that God would not leave them, but would attend them in their ministry with the demonstrations of his mighty power.

It is a general promise that greater works than he performed should be…”

“Greater works than these shall he do - So one apostle wrought miracles merely by his shadow, Act 5:15; another by handkerchiefs carried from his body, Act 19:12; and all spake with various tongues. But the converting one sinner is a greater work than all these. Because I go to my Father - To send you the Holy Ghost. John 14:15”

“14:12 Jesus promised that anyone who believes in him would perform great miracles and experience answers to their prayers (see 1 Jn 5:14). These things would become possible when Jesus went to the Father, because he would send the Holy Spirit to empower the works (John 14:16). • The greater works will not outdo Jesus’ work, but regular people empowered by the Spirit will be doing them. God promised that in the era of the Spirit, he would bring his Kingdom and power into the world in a way not seen before.”
