Agree, good post.
Nothing here about salvation, but about our walk. We walk because we want to be effective. We walk because we want to be like our Savior. We don't walk to gain or keep unmerited favor. Ephesians 2:8,9 Galatians 1:6 Romans 3:24 2 Timothy 1:9 1 Corinthians 4:7 That said, I agree, we walk in the Spirit and there is benefit from doing so both in our and others' lives. 1 Corinthians 12 is about body life. Romans 12:5
Walking in spirit is fruit.
So he is talking about salvation because Jesus says without producing fruit we will be burned.
There are many ways to explain about salvation because there are many ways to produce fruit. It seems most Christians don't realize about it.
"faith alone" faith is practically one time confession.
do you agree @lon?
