Making Beautiful

What does it mean to walk in the Spirit (Galatians 5:25)? Or sow to the Spirit (Galatians 6:8)?

At the very least, it means:

We must not get tired of doing good,
for we will reap at the proper time if we don’t give up.
(Galatians 6:9)

“Doing good” means fashioning or making something beneficial. It emphasizes action. Creating something excellent or beautiful.
