Those who are Christ's, those who have been crucified with Christ and thereby Christ lives in them, they have crucified and sacrificed their carnal selfish spirit. They have replaced Satan's way of get in order to live in God's sacrificial spirit of give. We could actually describe all of the fruits of God's Spirit listed in Galatians 5:22-23 as the fruit of humble sacrifice, devotion to God shown through the service to man. And God willing, we will tap into that maybe in the future.
A repentant attitude is not just an emotion. God is looking for fruits, not emotions.
We should be seeing these things in our lives in the way of fruit. They are foundational items of fruit to be produced by the converted person, but they are just the foundation. Everything else should be built on those fruits, especially on love.
