I have somewhat of a problem using Luke 22:36 in that manner. Many commentaries will tell you that Jesus was not speaking of physical weapons.Conflicting expectations? I don't know. It's certainly worth exploring if we consider that Jesus tells us to go strapped, and Paul tells us to be obedient in all things to employers who tell us not to go strapped. I think that is one of the reasons we have access to the Holy Spirit as a Helper.......to help us each answer such questions when we don't have all the answers ourselves....Luke, quoting Jesus Christ, wrote:Luke 22:36
English Standard Version (ESV)
36 He said to them, “But now let the one who has a moneybag take it, and likewise a knapsack. And let the one who has no sword sell his cloak and buy one.
Matthew Henry's Concise Commentary
Therefore, he that has a purse, let him take it, for he may need it. They must now expect that their enemies would be more fierce than they had been, and they would need weapons. At the time the apostles understood Christ to mean real weapons, but he spake only of the weapons of the spiritual warfare. The sword of the Spirit is the sword with which the disciples of Christ must furnish themselves.
But, as TAM said, we have to individually look to Jesus and seek understanding.
