There are so many questions and commentaries about miracles. I believe the One who is in charge of them all speaks a better word on the subject than me. I hope my thoughts honor God and come across as respectfully as they are meant.
I believe that the miracles are not random, but are teaching aids which immediately benefit those made in God's image. They are also used to complete prophecy or to prophecy future events. They are meant to catch the attention of hearts.
The miracles never veer from God's ultimate purpose, which is to reveal Himself and point us to eternal life. I don't believe miracles were done for the fun of it or for the immediate gratification of seeing something magical and new. No, I believe they point us away from themselves. They are meant to focus hearts on God.
Jesus does not practice medicine, but IS medicine as when he cures leprosy, heals the blind, makes the lame walk again and even raises the dead. "The dead" being defined as completely dead, not a person who is near death. He does not offer scientific conclusions for material phenomena, but IS materially phenomenal as He walks on water, calms a storm and turns water into wine! They are art and science rolled into one. They can comfort and confound hearts with no apology for doing either.
The rules and laws of nature are Christ's foundation, but He rises above them. God through Jesus does not break the rules or bend them. Christ, through obedience to the Father, perfectly commands the miraculous because Christ is God, perfect and holy. He does not cheat life, He
IS life! His aim is to capture hearts.
God uses the laws He created to point back to Him, The Creator! He is exceptional, not exemptional, if there is such a word. He meets the rule and His right-ness surpasses it-that's true exceptionalism! To break a rule He made would confuse us, so He does not do that -- He does not exempt Himself from the laws He created. His miracles rest on using what already is but is broken. Jesus heals the broken, whether healing a sinful heart or a broken body. His aim is to heal hearts.
What are current-day miracles? Should I pray for one? The short answer to the first question is: I don't exactly know, but I recognize one when it happens! The second is: Yes, particularly if you are praying for a God-shaped heart!
The heart that worships and obeys God no matter what is a present-day miracle!
