While at worship allow the world and it's possessions reframe from your thoughts. Bring a total worship of Spiritual sincerity and allow the God's peace in you life as you face the days ahead. For others whom are unable to attend worship today-- take moments to focus in prayers, or perhaps in songs with silent thoughts.
Think on this:
I seek the "center peace"which God brings over me. Therefore, I have presented my worship to Him, with His Truth.
"And let the peace of God rule in your hearts;" Colossians: 3:15 KJV
