Walk (peripateo): to habitually live and carry on in one general territory
Paul lived in an earthly body that was beaten and abused by his enemies, but in the spiritual realm he was recognized by the spirits and powerful in the name of Jesus to fight against the evil that came his way. You may feel small and limited in your daily life, but in the spiritual realm you can be just as powerful as Paul when you use the name of Jesus against those who are trying to oppress you daily. Everyday put on the loin-belt of truth, the shoes of peace, the breastplate of righteousness, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God.
“For though we walk in the flesh, we do not war after the flesh.” (2 Corinthians 10:3)
Remember that we may have earthly limitations with our flesh, but through the power of Jesus Christ we can do all things. (Philippians 4:13).
