I. Internal peace and external peace. In Jesus’ day for the Jews, peace was not just an internal state.
From Bible Study Tools website. The Meaning of Peace. In English, the word "peace" conjures up a passive picture, one showing an absence of civil disturbance or hostilities, or a personality free from internal and external strife. The biblical concept of peace is larger than that and rests heavily on the Hebrew root slm, which means "to be complete" or "to be sound." The verb conveys both a dynamic and a static meaning" to be complete or whole" or "to live well." The noun had many nuances, but can be grouped into four categories: (1) salom [l'v] as wholeness of life or body (i.e., health); (2) salom [l'v] as right relationship or harmony between two parties or people, often established by a covenant (see "covenant of peace" in Num 25:12-13 ; Isa 54:10 ; Ezek 34:25-26 ) and, when related to Yahweh, the covenant was renewed or maintained with a "peace offering"; (3) salom [l'v] as prosperity, success, or fulfillment (see Lev 26:3-9 ); and (4) salom [l'v] as victory over one's enemies or absence of war. Salom [l'v] was used in both greetings and farewells. It was meant to act as a blessing on the one to whom it was spoken: "May your life be filled with health, prosperity, and victory." As an adjective, it expressed completeness and safety. In the New Testament, the Greek word eirene [eijrhvnh] is the word most often translated by the word "peace." Although there is some overlap in their meanings, the Hebrew word salom [l'v] is broader in its usage, and, in fact, has greatly influenced the New Testament's use of eirene [eijrhvnh].Jesus said a lot about peace.
II. The cross of Christ is the instrument of peace but also a cause for strife.
Roman 5:1 Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ,
Colossians 1:20 and by Him to reconcile all things to Himself, by Him, whether things on earth or things in heaven, having made peace through the blood of His cross.
III. The Bible contrasts the real peace and the counterfeit peace of the world.
IV. The peace of spiritual life now is a goal and condition of the fulfilled Christian experience and forecasts the eternal peace of the kingdom later. The promise of his coming is the source of peace.
Multiple verses place peace in the center of our obedience.
Galatians 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control
Romans 8:6 For to be carnally minded is death, but to be spiritually minded is life and peace.
Philippians 4:7 and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus
V. If we have this peace, we should tell others.
J9 Then, the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled,[b] for fear of the Jews, Jesus came and stood in the midst, and said to them, “Peace be with you.” 20 When He had said this, He showed them His hands and His side. Then the disciples were glad when they saw the Lord. So Jesus said to them again, “Peace to you! As the Father has sent Me, I also send you.”
I don’t think “Peace to you” is just a normal greeting here like “Hey there!” I think it is the basis of everything. One, they were probably terrified. He says it twice, after appearing and then after proving he was in a physical body. The nature of his physical body is a study in itself, but while physical it transcends certain rules of time and space.
Conclusion: Am I living in peace-less-ness? Yes. Worry, anxiety, envy anger gossip. Tenseness of muscles. Thes are the opposite of peace.
From looking at these verses I can see how central to the Biblical world view “peace” is. It is to be a goal in our personal spiritual lives. It is one of the bases of the gospel, one of the purposes of the cross.
I am angry with a new boss. I have not been living in peace with this person, at least not internally. I have sinned in not living with a peaceable spirit and cannot get that back, only apologize and repent.
