Do miracles prove obedience to God?

The Master stated the following while He was on the earth in the 1st century:

"Not everyone who says to Me, 'Lord, Lord,' will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter. "Many will say to Me on that day, 'Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?' "And then I will declare to them, 'I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.' " (Matthew 7:21-23 NASB)

"And he said, 'Then I beg you, father, that you send him to my father's house--for I have five brothers--in order that he may warn them, so that they will not also come to this place of torment.' "But Abraham said, 'They have Moses and the Prophets; let them hear them.' "But he said, 'No, father Abraham, but if someone goes to them from the dead, they will repent!' "But he said to him, 'If they do not listen to Moses and the Prophets, they will not be persuaded even if someone rises from the dead.'" (Luke 16:27-31 NASB)

The Apostle Paul, under the inspiration of the Holy Spirit, wrote the following:

"For the secret of lawlessness is already at work – only until he who now restrains comes out of the midst. And then the lawless one shall be revealed, whom the Master shall consume with the Spirit of His mouth and bring to naught with the manifestation of His coming. The coming of the lawless one is according to the working of Satan, with all power and signs and wonders of falsehood, and with all deceit of unrighteousness in those perishing, because they did not receive the love of the truth, in order for them to be saved." (2 Thessalonians 2:7-11 The Scriptures)

Interestingly, John the Baptist (the 2nd Elijah to come) did no miracles (John 10:41)?
