"If we live in the Spirit, let us also walk in the Spirit." - Galatians 5:15
This goes really well with the verse from a few weeks ago. Having accepted by faith the free gift of salvation through the blood of Jesus Christ, we are now host to the Holy Spirit.
Because we live with the Holy Spirit living in us, it only makes sense that we should strive to walk in the Spirit, being sensitive to His promptings and daily walking in what He shows us through God's Word.
"Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
"He shall glorify me: for he shall receive of mine, and shall shew it unto you." -John 16:13-14
