““Neither Jesus nor Paul nor John point to activity in the church or miracles as evidence of regeneration. They rather point to character traits in life. In fact, immediately after the verses quoted above Jesus warns that on the day of judgment many will say to him, “Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?” But he will declare to them, “I never knew you; depart from me, you evildoers” (Matt. 7:22–23). Prophecy, exorcism, and many miracles and mighty works in Jesus’ name (to say nothing of other kinds of intensive church activity in the strength of the flesh over perhaps decades of a person’s life) do not provide convincing evidence that a person is truly born again. Apparently all these can be produced in the natural man or woman’s own strength, or even with the help of the evil one. But genuine love for God and his people, heartfelt obedience to his commands, and the Christlike character traits that Paul calls the fruit of the Spirit, demonstrated consistently over a period of time in a person’s life, simply cannot be produced by Satan or by the natural man or woman working in his or her own strength. These can only come about by the Spirit of God working within and giving us new life.””
