Fruit of the Spirit = proof of indwelling
When we abide in Christ we are to produce the 'Fruit of the Spirit' as described in John 15 and Galatians 5:22-23. We don’t automatically have this fruit but surprisingly neither do we have to ask for it! We are called to develop spiritual gifts after we come to Christ as a life long miraculous journey.
The indwelling Holy Spirit has incredible connection with our commitment of making Christ the Lord of our life (Romans 12:1-2). When we submit to the Holy Spirit we begin to produce the fruit of the spirit. When we come to Christ the indwelling of the Holy Spirit is automatic, but we have to work through submission to God by studying the word and learning Gods voice to receive the gifts. You can always have confidence in people who both know the Bible, hear God and have a testimony of miraculous stories that involve healing and deliverance to the Glory of God: The proof is in the fruit!
