Therefore being justified by faith, we have peace with God through our Lord Jesus Christ. Romans 5:1
Christ is "the Prince of Peace" (Isaiah 9:6), and it is His mission to restore to earth and heaven the peace that sin has broken. "Being justified by faith, we have peace with God through our Lord Jesus Christ" (Romans 5:1). Whoever consents to renounce sin and open his heart to the love of Christ, becomes a partaker of this heavenly peace.
There is no other ground of peace than this. The grace of Christ received into the heart, subdues enmity; it allays strife and fills the soul with love. He who is at peace with God and his fellow men cannot be made miserable. Envy will not be in his heart; evil surmisings will find no room there; hatred cannot exist. The heart that is in harmony with God is a partaker of the peace of heaven and will diffuse its blessed influence on all around. The spirit of peace will rest like dew upon hearts weary and troubled with worldly strife.
Christ's followers are sent to the world with the message of peace. Whoever, by the quiet, unconscious influence of a holy life, shall reveal the love of Christ; whoever, by word or deed, shall lead another to renounce sin and yield his heart to God, is a peacemaker. (Thoughts from the Mount of Blessing, 27, 28)
Reflection: A spirit of peace is evidence that we have a connection with heaven.
