Lots of people think they have the Holy Spirit. Their proof for this is that they experience healing, hear a voice from God, get inner directions to a shortcut to Wal-Mart and other such things.
All of these may indeed be a sign of something, but they are not necessarily a sign you have the Holy Spirit.
One of the first ways to know the Holy Spirit is at work in you is that sin really bugs you. When Jesus said He would send another Comforter who would “reprove the world of sin,” I’d begin with your proof of having the Spirit right there.
“Reprove” means to “convict, refute, confute a) generally with a suggestion of shame of the person convicted b) by conviction to bring to the light, to expose,” according to Thayer’s Lexicon.
In other words, the Spirit makes you feel bad about your sin, exposes it for what it is and it is ugly.
Healing a knee problem or hearing an inner voice giving you the “OK” to quit your job is more exciting than feeling bad about sin, which is why we go with the first group of proofs.
But true spiritual living sees that our body is the temple of the Holy Ghost, so shape up. What fellowship has light with darkness, righteousness with unrighteousness? None at all.
The presence of the Spirit in your life will always result in you having a huge problem with your own sin to the extent that not doing sin becomes way more enjoyable and comfortable than the fleshly pleasure of doing sin.
A sign the Spirit has not moved in is when other people’s sins bother you more than your own. When your sin doesn’t even phase you. When you live with a total lack of remorse over your behavior that fails to meet God’s standards.
I know, I know, it’s more fun to speak in tongues, but hey, that’s what the Book says.
