Today, May 3rd is the National Day of Prayer. It falls on the first Thursday every May and this year that is the 3rd. The annual day of prayer was first recognized in 1952 when it was created by a joint resolution of the U.S. Congress and signed into law by President Harry S. Truman. It wasn't decided to be the 1st Thursday in May until 1988 when President Ronald Reagan moved it's date.
This year's theme for 2018 is "Unity". Organizers made a statement saying: "In 2018, our theme will be Pray for America - UNITY, based upon Ephesians 4:3 which challenges us to mobilize unified public prayer for America, "Making every effort to keep the unity of the Spirit through the bond of peace,".
President Trump signed the proclamation and wrote the following:
Events will be held all across the country today in honor of the National Day of Prayer. The National Observerance of the National Day of Prayer will be held in Statuary Hall in the U.S. Capitol. It begins at 7:30pm. Multiple politicans and officials will be in attendence.
