All sorts of hucksters do things in the name of Jesus.
Doesn’t mean they have salvifivc faith. Tons of people go through seminary, preach and teach. At some point they fall away and admit they never believed.
HMMMmmm...
Jesus answered, The work of God is this: to believe in the one he has sent.
1 John 3:21-24
Dear friends, if our hearts do not condemn us, we have confidence before God and receive from him anything we ask, because we keep his commands and do what pleases him. And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us.
