Not Everyone Who Says to Me, Lord, Lord

On that day, many will say to me, Lord, did we not prophesy in your name? Cast out demons in your name?" And then I will declare to them, I never knew you. Apart from me, you workers of lawlessness. This is why I started teaching the Bible as a high school student. By teaching, I mean, dude, I just read this yesterday. Look at what it says. It's actually treating him as Lord, obeying him. Doing the will of the Father in heaven.
