The question was "How do you know which leaders to obey?"
In John 14:21, Jesus said "He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him."
Regardless of what people claim, those who truly love Jesus are willing to obey Him. And Jesus manifests Himself to those who obey Him. So, one way to know God's will RIGHT NOW is to obey Him.
But two verses later, Jesus clarifies His statement: "If anyone loves Me, he will keep My word;"
Those who truly love Jesus obey Him, and they keep His Word. So, which leaders should you obey? A leader who does not stand without compromise for the Word of God doesn't really love Jesus. Therefor, Jesus doesn't manifest Himself to that leader. Therefor, you shouldn't be following that leader.
