Matthew 7:22-23 says, Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
When a person walks in signs and wonders, prophesy, deliverance, or ministry does not confirm that he is in relationship with the person Jesus. How, who, and what a person loves, is what confirms his relationship with God.
