Yes, miracles do still happen today, and we don’t have to wait for a prophet to come around to perform them on us. After Jesus died and rose again, before he ascended into heaven, he promised to send a comforter (the Holy spirit) that would live in us. Once we receive this comforting spirit of God, all we have to do is call on Him, and He WILL answer.
“Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. If ye shall ask any thing in my name, I will do it.
If ye love me, keep my commandments. And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him for he dwelleth with you, and shall be in you.
I will not leave you comfortless: I will come to you. Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
At that day ye shall know that I am in my Father, and ye in me, and I in you.” John 14:12-20
“Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?” 1 Corinthians 3:16
