John 7:17 If anyone wills to do His will, he shall know concerning the doctrine, whether it is from God or whether I speak on My own authority.
If what you are doing is from God, it will agree with the word. James 3:14-15 But if you have bitter envy and self-seeking in your hearts, do not boast and lie against the truth. This wisdom does not descend from above, but is earthly, sensual, demonic.
The Word of God remains. Luke 21:33 Heaven and earth will pass away, but My words will by no means pass away.
What I want to do looks good but is it from God. Proverbs 14:12 There is a way that seems right to a man, But its end is the way of death.
