Many people desire peace, but few find it. People's actions and attitudes contribute directly to peace, but it is ultimately a gift from God. The wars and conflicts in humanity will never end until Christ establishes true, lasting peace, which will be rewarded to all who put their trust in Him. When we focus our minds on God beyond our circumstances, we trust Him to help us no matter what. The confidence we have that God will work all things out for our best interests brings peace into our hearts. 
We have God's perfect peace through our Lord Jesus Christ as He made it possible for all humanity to have relationships with God. The Lord Jesus Christ procured peace for us on the cross of Calvary, and that peace is conveyed to our hearts and minds by the Holy Spirit. By trusting Jesus Christ as our Lord Savior, we are clothed with His righteousness and live in the peace of God. The peace will not last if our trust in Him is temporary and unsteady. Only by steadfast faith in the Lord will we be kept in His perfect peace.

Dear Heavenly Father, help me keep my mind on you. Protect me from evil thoughts that will pull me away from you. I am at perfect peace when I am close to you. As you fill my heart with peace that goes beyond all worldly understanding, I pray that you will allow others to see the greatness of You.
In Jesus's name I pray. Amen.
