That's what Jesus taught and that's what I tend to do,.. however,.. I don't think He meant for us to constantly be doormats and take crap from other people either. I mean, just look how angry He got when His temple was being used for a marketplace. It was justified anger. So,.. how do we know when our anger is justified or to simply walk away? Any ideas?
A "Christian's" conscience is supposed to be directed by the Holy Scriptures.....as that is how the Holy Spirit communicates God's will. Why? A Christian knows and comprehends through those Holy Words that he will be judged by those same scriptures.....so the Christian should want to be sure that his actions are authorized by God. (John 12:48)
What do the scriptures have to say about the use of force and or violence by a Christian? Violence should never be the first course of action, it depends upon the situation and whether you are in mortal danger or are simply being insulted with no personal violence directed at you. Its one thing to turn the other cheek when you have only been insulted such as a slap on the face (Matt.5:38-39).......physical retribution is not called for.......and its another when someone places your life and or property in danger. One has the right to defend both. As detailed by the Christ Himself (Luke 11:21) The Christ taught in a parable format, "When a strong man, fully armed, guards his own palace (home), his goods are in peace."
Then we are instructed to defend first and foremost our Household/Families (1 Tim. 5:8) Anyone that does not is worse than an infidel.
A good example of turning the other cheek would be found in (Luke 9:51-56) A Samaritan village refused to allow Jesus and His disciples to stay overnight..........2 of Christ's disciples (James and John) became angered and asked the Lord if they should command fire from heaven destroy the village? Christ responded, "You do not know of what spirit you are.........The Son of Man did not come to destroy men's lives but to save them". An insult does not constitute mortal danger.
Being wronged for the sake of the Gospel is nothing new to a Christian......but again, being rejected because of your faith is one thing and being physically threatened via mortal danger is another.
Some people falsely teach that Christianity is a religion of Pacifism........Truth as revealed from heaven was the very mission statement of Christ Jesus. He never instructed total pacifism. Nor has God instructed such. As the scriptures tell us there is a time for everything to include the necessity of killing through righteous justification. (Eccl. 3:3)
God has authorized the world government to bear the sword in a punitive manner (even up to capital punishment) -- Romans 13:1-4
He permits Christians to work for government and military organizations (Luke 3:14; Acts 10:1-8, 34-38, 11:18). And again God charges us with providing and protecting our own households. (1 Tim 5:8)
Jesus even demanded that His disciples ARM THEMSELVES when arms for self defense was required (Luke 22:35-36)
Conclusion: "To everything there is a season, and a time to every purpose under heaven; A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted, A TIME TO KILL, AND A TIME TO HEAL, A TIME TO BREAK DOWN, A TIME TO BUILD UP.........."
A Christian's duty is to discern the time and place for all these natural events.........via allowing the Holy Spirit to live within you. How does that Spirit live in you? You get your directions from the Holy Scriptures that are a direct product of inspiration from the Holy Spirit. If you allow those words to live in, guide you, and come first with every situation encountered.......what spirit other than the Holy Spirit is directing your path? Your mind is a product of your spirit.......when you allow the Spirit of God to live in your mind.....only then can you be directed by God. You are free to accept or reject that Spirit and your own risk. Man is not capable of guiding his own steps. (Jer. 10:23)
