The only one that perform miracles is God. No human has any miracle power in them. God might use people to perform the miracle but it isn't from that person. It doesn't matter if the miracle is big or small, it is from God. He might help you when you are a little short in money or by taking away the cancer that the doctors don't know what to do with.
Great is our Lord, and abundant in power; his understanding is beyond measure.
God is all powerful. Humans are not because we are not perfect in the least bit.
Yes there is miracles still today but, they aren't performed by humans and it doesn't matter who says what. Miracles are performed by God to draw us closer to Him and to show His great power.
I hope that made sense!
God bless you all
