The peace of God is something that not only surpasses all understanding but exceeds our natural ways. This peace exceeds the natural and causes us to remain calm regardless of our circumstances. It guards the heart. We do not lose our minds, and our hearts beat as it should.
The peace of God orients us and keeps us focused on Christ. The result is peace in the midst of adversity. Problems may continue, and there may not be an exact day or time for how long our situation will be, but our life does not depend on knowing when the difficulties we are going through will end. Our life depends on God. Having the peace of God allows us to stay calm and safe in the midst of trouble.
It does not mean that as Christians, we will not experience hardships anymore, and problems will no longer be part of our lives. The apostle Paul does not teach a gospel as a good luck charm, where everything will be perfect. Those who are with Christ can go through the same struggles as any other person but the difference is Christ, who is the peace of God, produces the effect of life in the spirit. A different reality which surpasses all understanding.
And the peace of God, which transcends all understanding will guard your hearts and your minds in Christ Jesus. Philippians 4:7
