Romans 10:15 - And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!
Paul, under Holy Spirit inspiration, quotes from both Isaiah 52:7 & Nahum 1:15. While the foot is not considered beautiful by most, it is by our Lord when our feet take us away from evil (Psalm 1:1), to the House of the Lord (Ecclesiastes 5:1), and from the House of God to those who are in the highways and hedges (Luke 14:23). May we each have beautiful feet in the sight of the Lord.
