Thanksgiving. What do you think of when you hear that word? The first thing that pops into my mind is turkey and pumpkin pie. But I don't think that's what Paul is talking about when he says in Philippians 4:6, "Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God." Or when David says in Psalm 69:30, "I will praise the name of God with a song; I will magnify him with thanksgiving." I don't think they're talking about praying while eating candied yams, or magnifying him with mashed potatoes. No, they're talking about thanks-giving, giving thanks to the Lord.
Dictionary.com defines thanksgiving as "the act of giving thanks; grateful acknowledgment ... especially to God." Well that's pretty much it in a nutshell. The thing is, thanksgiving
"Enter his gates with thanksgiving, and his courts with praise! Give thanks to him; bless his name!"
~ Psalm 100:4
