Galatians 5:22-23 refers to the fruit of the Spirit and list the nine aspects of that fruit. They are all character qualities and each one is very apparent in Jesus' character.
These character qualities are the fruit (or, the result) of the Holy Spirit working in the life of the Christian, transforming him/her to become more like Jesus. In that sense, they are indicators of spiritual maturity.
This page deals with the Fruit of the Spirit in general. Another page contains teaching series that deal with each aspect of the fruit individually and there are pages dedicated to each aspect (see the buttons above).
