This does warn us against vigilante actions, but Christ was no pacifist. He bracket His public ministry between two violent clearings of the Temple courts of money changers and animal sellers, in which He specially made a whip to cause pain for the enforcement of His instructions. Some very sincere believers have felt that it would be better after all to simply trust the Lord for one's survival in this world. There is absolutely no hope without trust in God's protection. But trust is not a substitute for obedience.
Obedience is the outward evidence of genuine trust.
To not flee when the option is available, is not faith or confidence in God, it is disobedience to the Lord. Faith is therefore not passivity that resigns to circumstance in the expectation of being rescued by God. Nor is it bravado that takes authority into its own hands, as Peter well-meaningly did. Both are sins of presumption.
