A heart at peace is contrasted with envy. As a noun envy is a feeling of discontented or resentful longing aroused by someone else’s possessions, qualities, or status. As a verb envy is a desire to have a quality, possession, or another attribute belonging to someone else. Envy is never satisfied. Envy always wrongfully believes more will bring peace. Envy wrongfully believes those who have what they desire are happy. Envy rots the bones.
A heart is at peace when it is content and thankful for what God has done. Peace is the state of being one with God for he is enough. Peace is knowing and accepting God’s love and grace for it is enough. A heart at peace knows God and his one and only Son, Jesus the prince of peace. A heart at peace gives life to the body. Life to the body is the health effects of fearing the Lord and walking in his wisdom (3:7-8, 16-18).
Since all this is true, I am thankful to have time to be one with God every morning, if I stop to do it. The choice is mine. He is always there waiting for me to find his peace.
