Jesus said that you know the Holy Spirit.
The world, not so much. Not only can they not receive Him, but they can't even perceive Him.
But, as soon as you come to Christ, you know the Holy Spirit, because He is not only with you, but He is in you.
You do understand what this means, right?
The wisdom of God is in you. When you come up against a challenge, you already have the answer.
The power of God is in you. The same Spirit that raised Jesus from the dead is still working miracles through you.
How does this become reality in your life? Only by faith.
You can't wait until you feel like you know the Holy Spirit. You have to believe what John 14:17 says, regardless of your feelings.
You know the Holy Spirit. Jesus said you do, and He doesn't lie.
