In service today you may be honoring, All Saints Day (November 1st). Later, you might be heading out to gather candy with your children in some fashion or another... but for a time today, just focus on the Lord.
David says it best:
Psalm 103:1 (ESV)
"Bless the Lord, O my soul and all that is within me, bless His holy name!"
Psalm 103:8-13 (ESV)
The Lord is merciful and gracious, slow to anger and abounding in steadfast love.
He will not always chide, nor will He keep His anger forever.
He does not deal with us according to our sins, nor repay us according to our iniquities.
For as high as the heavens are above the earth, so great is His steadfast love toward those who fear Him;
as far as the east is from the west, so far does He remove our transgressions from us.
As a father shows compassion to his children, so the Lord shows compassion to those who fear Him.
