I expect more from you. To whom much is given much is expected.
There is always a reason for God to do or not to do in the affairs of men. Jesus did not perform miracles before the Pharisees because they were religious and only interested in protecting what they had through religion. Not much different than todays organized church.
A rebuke followed by wild speculation on your part. Why don't you just stick with what the Bible says? Where does the Bible say that Jesus never did any miracles when the Pharisees were around? Wasn't blinding the Pharisee Paul a miracle? Nicodemus was a Pharisee. He was familiar with Jesus' miracles. He said to Jesus, "Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him." Whether he saw them or not, we don't know. Jesus refusing to give a sign for the Pharisees and Saducees on one occasion does not mean He never did any miracles before Pharisees when he was ministering in the synagogues and other places.
Anyway, the Bible is holy. Jesus is holy. We shouldn't just make statements up about what Jesus did or did not do without some reason for knowing it. And you shouldn't make up reasons for why Jesus did or did not allegedly do something, unless this has clearly been made known to us. I Corinthians 15 indicates being a false witness of God is a bad thing. Being a false witness of Christ would not be a good thing, would it?
The miracles Jesus did were to fulfill prophecy and to proclaim Him as the promised Messiah.
What would be the purpose of such miracles today?
Here we are again with you thinking you can pronounce THE purpose of miracles, as if you have the authority to choose one purpose and make that the only one.
Jesus also did miracles that demonstrated His compassion.
When you read this do you come away with the impression that the actual woman being healed wasn't part of the purpose of her being healed?
Luke 13
15 The Lord then answered him and said, “Hypocrite! Does not each one of you on the Sabbath loose his ox or donkey from the stall, and lead it away to water it? 16 So ought not this woman, being a daughter of Abraham, whom Satan has bound—think of it—for eighteen years, be loosed from this bond on the Sabbath?”
What reason does Jesus give for the man being born blind? Notice that he was healed.
John 8:3a
Jesus answered, Neither hath this man sinned, nor his parents: but that the works of God should be made manifest in him.
Acts 4:33
And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.
Can you give me one scripture or even one reason why miracles today can't bear witness to the same sorts of things they bore witness to in Biblical times?
