Then God’s peace, which goes far beyond anything we can imagine, will guard your hearts and minds in union with the Messiah Jesus.
4Keep on rejoicing in the Lord at all times. I will say it again: Keep on rejoicing! 5Let your gracious attitudec be known to all people. The Lord is near: 6Never worry about anything. Instead, in every situation let your petitions be made known to God through prayers and requests, with thanksgiving. 7Then God’s peace, which goes far beyond anything we can imagine, will guard your hearts and minds in union with the Messiah Jesus. 8Finally, brothers, whatever is true, whatever is honorable, whatever is fair, whatever is pure, whatever is acceptable, whatever is commendable, if there is anything of excellence and if there is anything praiseworthy—keep thinking about these things. 9Likewise, keep practicing these things: what you have learned, received, heard, and seen in me. Then the God of peace will be with you.
God’s peace guards our hearts and minds.
Before we we were born again, we were without hope and without God in the world. Ephesians 2:13 Then Messiah Jesus came.
The whole armor of God
In concluding his letter to the Ephesians, Paul used military terms reveling God’s whole armor we put on in order to be strong in the Lord and in His mighty power. One piece of our armor is our feet fitted with the readiness of the gospel of peace.
10Finally, be strong in the Lord and in His mighty power. 11Put on the full armor of God, so that you can make your stand against the devil’s schemes. 12For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world’s darkness, and against the spiritual forces of evil in the heavenly realms.
13Therefore take up the full armor of God, so that when the day of evil comes, you will be able to stand your ground, and having done everything, to stand. 14Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness arrayed, 15and with your feet fitted with the readiness of the gospel of peace. 16In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17And take the helmet of salvation and the sword of the Spirit, which is the word of God.
18Pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints. Ephesians 6:10-18
The Hebrew word for God’s peace is shalom.
Shalom is a word full of rich meaning of which much is lost in the English translation. Howard Snyder has written books about it. Here’s just a taste of his spiritual insight.
The Old Testament teaches that God’s plan is to bring a universal peace (shalom) to his creation. This means more than the absence of conflict and immensely more than “inner peace” or “peace of mind. “In the Old testament sense, shalom might be called an ecological concept. It carries the sense of harmony, right relationship and the proper functions of all elements in the environment.
When it speaks of the gospel of peace, the New Testament builds on the shalom promises of the Old Testament. The apostle Paul, for instance, tells us that the kingdom of God is “righteousness, peace and joy in the Holy Spirit” (Rom 14:17). Peace is at the heart of God’s reign.
The New Testament theme of peace ties the kingdom directly to Jesus Christ. To know Jesus is to be in the kingdom. At Jesus’ birth the angels announced “peace on earth” as the meaning of Jesus’ coming (Lk 2:14). Jesus is the Prince of Peace (Is 9:6); like Melchizedek he is “King of Peace” (Heb 7:2). God reigns through Jesus Christ, and the meaning of that reign is peace. Excerpts from: The Kingdom as Shalom Howard Snyder
Wisdom none of the rulers of this world has known.
6Among the mature, however, we speak a message of wisdom—but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7No, we speak of the mysterious and hidden wisdom of God,a which He destined for our glory before time began. 8None of the rulers of this age understood it. For if they had, they would not have crucified the Lord of glory. 9Rather, as it is written:
“No eye has seen,
no ear has heard,
no heart has imagined,
10But God has revealed it to us by the Spirit. The Spirit searches all things, even the deep things of God. 11For who among men knows the thoughts of man except his own spirit within him? So too, no one knows the thoughts of God except the Spirit of God. 12We have not received the spirit of the world, but the Spirit who is from God, that we may understand what God has freely given us. 13And this is what we speak, not in words taught us by human wisdom, but in words taught by the Spirit, expressing spiritual truths in spiritual words.
14The natural man does not accept the things that come from the Spirit of God. For they are foolishness to him, and he cannot understand them, because they are spiritually discerned. 15The spiritual man judges all things, but he himself is not subject to anyone’s judgment. 16“For who has known the mind of the Lord, so as to instruct Him?” But we have the mind of Christ. 1 Corinthians 2:6-16
