Ever wished you had expressed "thanks" to someone, but you didn't when you could have/should have done so? I think we all have "been there, done that!'
Thinking about Thanksgiving - what are you thankful for now that at one time you were very unthankful? Is there something God didn't allow you to have and now you're very thankful He didn't? What or who are you missing now, but you're thankful for the minutes, days, years you did enjoy that person or that thing? What are you willing to say "thank you" for and it hasn't even happened yet? Think about Philippians 4:6, "Be anxious for nothing, but in everything with prayer and supplication with thanksgiving, let your requests be made known unto God." That's thanking the Lord for the answer He will give.
1 Timothy 4:4, "For every creature of God is good, and nothing is to be refused if it is received with thanksgiving."
