Jesus or the author of John don’t judge it at all the way you do. It says God’s angel was performing the healings. Sounds pretty legitimate to me. We have to accept the Bible, it’s wrong to judge the Word of God based on your preconceived biases.
Places of power are a proven fact of the Bible.
Well, hang on. Early manuscripts of the Gospel of John don't contain the end of
verse 3 and
verse 4 which is why many translations of the Bible such as the NASB, the ESV, the NIV, the NRSV, and the NET leave out this portion of the account entirely, and the rest, generally, make a notation to the effect that there is manuscript inconsistency concerning the bit about a "messenger" or "angel" stirring the water of the pool.
But this aside, again, there is no prescription in the account of Jesus healing the man at the Pool of Bethesda about seeking "sacred places" for healing. Nowhere in the account does it say, "And all people ought likewise to seek healing in holy places." Instead, the invalid man waiting at the pool was not healed by the "sacred place" but by
the Person of Christ. If, then, there is any prescription one might form from the story it would be that
Jesus is the "Great Physician," healing is found in him, not in superstitious hope in the power of a "sacred place."
