Maybe the best indicator of our spiritual maturity is not how often we attend church or how many Scripture verses we've memorized, but the growth of the Fruit of the Spirit in our character, attitudes, and actions.
The Holy Spirit gives gifts to Christ-followers in order to serve the Body of Christ, the Church.
Being filled with the Holy Spirit is a vital but not automatic experience that must be done continually.
What we do here and now matters — it will not go to waste — because Jesus Christ is risen from the dead and he will come again.
