Jesus had an outstanding healing ministry while walking the shores of Galilee, most of the miracles where public, but most importantly Jesus was not afraid of verification.
The gifts of Healing operating today should also not be afraid of medical verifications, it is wise to tell people sometimes who are in a "hurry" to share testimonies to go back to the Dr and confirm, do test, if it's the power of God the Dr's would affirm same.
Go Show Yourself to the Priest
Even though Jesus was the creator, He recommends that the healed man obtain a priestly verification according to the law of Moses.
"He looked at them and said, "Go show yourselves to the priests." And as they went, they were cleansed of their leprosy." Luke 17:14.
He could have asked the man to show himself to his family etc but they were not in a position to verify and validate, especially if the man is to be integrated into society. You can compare Luke 5:14, even when he said show no one, Jesus said for him to go show himself to the priest.
As ministers of God we must make sure we are ethical in all our dealings, doubters would have their field day, but whatever we can do to reduce this would enhance the Gospel so as not to put a stumbling block. This can and should include the need to be open for proper verification by qualified authorities.
When Jesus was on the earth, he raised three people from the dead. He raised the widow’s son in the village of Nain (Luke 7:15). He raised the 12-year-old daughter of Jairus, a ruler of the synagogue (Mark 5:42). He raised Lazarus, the brother of Mary and Martha in Bethany after he had been dead four days (John 11:44).
Two of these were in public glare, and he did ask that stones be rolled away publicly and we have scripture account for this.
*Miracles can and should be verified once motives is pure and it is the power of God.
* We must operate in very ethical manner not to put a stumbling block on the path of the Gospel.
*Miracles are still valid manifestations of the Word of God.
*The Word must hold preeminence, miracles must never be proof of authenticity, but yet the authentic would have signs and wonders following.
