Peace is defined as a state of calm and harmony between your mind, body, and soul. The Greek word for peace is εἰρήνην (eiréné) which can be interpreted as “. . . the tranquil state of a soul assured of its salvation through Christ, and so fearing nothing [apart] from God and content with its earthly [circumstances]. . .”
Before Christ is arrested and crucified, He takes the time to remind His disciples in John 14 that He is leaving them with peace. Now, Jesus did not have much time to waste, and you would think that He would have used what little time He had left to remind the disciples of the importance of love, forgiveness, or prayer, but instead he reminds them of His peace.
So, why does Jesus highlight peace before the cross? Because He knew that this world would try to substitute His peace with one that is contrary to His teachings.
The Peace the World Gives
Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. - John 14:27 NIV
The peace the world gives are really problems designed to look like solutions. The peace of this world tells us that if we just get married that we will be happy, that if we get the job, we will be fulfilled, or that if we get more money, we will not have any more difficulties. All those things require you to work in-order to obtain peace, but Christ informed us that peace is a gift that He gives us, meaning it is something we accept and not work for.
The Peace That God Gives
The peace that God gives does not equate to the absence of problems; instead, it requires us to acknowledge His presence in our problems. God’s peace is the type of peace that will allow you to sleep in the middle of a storm (Matthew 8:24), that will give you the confidence to face your giants and allow you to declare; regardless of your situation and circumstances, that all things will work out for your good (Romans 8:28).
So, if you want peace in your life, do not look for it in people or things, instead accept it from God.
