Living and Walking by the Spirit

Galatians 5:25 NASB
If we live by the Spirit, let us also walk by the Spirit.

What do we live by?
Who should walk by the Spirit?
What should those who live by the Spirit also do?
How do we walk?
What phrase is repeated in this short verse?

Here is Wuest's word-for-word English translation of the Greek for verse 25:
In view of the fact that we are being sustained in spiritual life by the Spirit, by means of the Spirit let us go on ordering our conduct.

I looked up "live" and "walk" for this verse in Strong's.
Live G2198 zao to live (literally or figuatively)
Walk G4748 stoicheo to march in (military) rank (keep step), i.e. (figuratively) to conform to virtue and piety

Now let's relate this verse to its context.
What has Paul just said has happened to our flesh in verse 24?
Read what Paul wrote in Galatians 2:19-20.
So, if our flesh has been destroyed, how is it that we live?
From where did we get that Spirit? See Galatians 4:6.
Who made it possible for us to obtain that Spirit? See Galatians 3:13-14.
In Galatians 1:3-5, what did Paul tell the Galatians that Christ had done for them?
Why did Paul say that Christ did that?
What are some of the deeds of this present evil age? See Galatians 5:19-21.
If you're living and walking by the Spirit, what is your relationship to these behaviors?
What does Paul remind us of in Galatians 5:16?
And what evidence will the world see if we are walking by the Spirit? Read Galatians 5:22-23.
What did Paul say others did when they saw the changes that had taken place in his life after he became a Spirit-filled follower of Christ? See Galatians 1:23-24.

As you live by the Spirit today, pray that you will also walk by the Spirit, so that others will be glorifying God because of you.
