The Christian greeting

Paul the apostle wrote the most epistles.  He had a standard greeting that is found in almost all of them.  It is "Grace to You and Peace from God Our Father and the Lord Jesus Christ".  Here's the 10 places I found the phrase:

Rom. 1:7; 1 Cor. 1:3; 2 Cor. 1:2; Gal. 1:3; Eph. 1:2; Phil. 1:2; Col. 1:2; 1 Th. 1:1; 2 Th. 1:2;
​Philem. 1:3
Within this phrase is the essence of the Gospel.  On the one hand is God's activity toward us.  GRACE.  The unmerited favor of God.  On the other hand is our response to that GRACE...... PEACE.  The anxiety that sin brings is gone.  The joy and peace that comes from believing is the result of having experienced what the hymnwriter called:  "Wonderful Grace of Jesus, Greater than all My Sin". Praise God!
