One clear way to find out is to come to Jesus and ask him to search you and reveal anything spiritually unhealthy, anything unholy, in you. Opening ourselves up to the light of his scrutiny, to the truth of his Light, gives us a remarkable sense of freedom. We don't have anything to hide. Then God can do some truly remarkable things in us and through us because there are no distorted motives.
The Bible says - John 3:20-21 Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. 21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God.
