Why should we give thanks? No, rather, the question is, Why shouldn't we give thanks? God has done so much for us that we would be most ungrateful not to acknowledge His blessings. If you are reading this right now, you have at least one wonderful, precious gift: life. Even if you had nothing else, that in itself would be enough to warrant everlasting praise to the One who created you and who gave His life so that you could live, both here and eternally. But that isn't all you've been given. Health, family, friends, freedom to worship God as you choose—and these are only a very few of the many blessings you have. I'll leave you to think of more. There are numerous passages of Scripture listing still more reasons we ought to give thanks. Here's just one of them:
Bless the LORD, O my soul: and all that is within me, bless his holy name.
Bless the LORD, O my soul, and forget not all his benefits:
Who forgiveth all thine iniquities; who healeth all thy diseases;
Who redeemeth thy life from destruction; who crowneth thee with lovingkindness and tender mercies;
Who satisfieth thy mouth with good things; so that thy youth is renewed like the eagle's.
The LORD executeth righteousness and judgment for all that are oppressed.
He made known his ways unto Moses, his acts unto the children of Israel.
The LORD is merciful and gracious, slow to anger, and plenteous in mercy.
He will not always chide: neither will he keep his anger for ever.
He hath not dealt with us after our sins; nor rewarded us according to our iniquities.
For as the heaven is high above the earth, so great is his mercy toward them that fear him.
As far as the east is from the west, so far hath he removed our transgressions from us.
Like as a father pitieth his children, so the LORD pitieth them that fear him.
For he knoweth our frame; he remembereth that we are dust.
As for man, his days are as grass: as a flower of the field, so he flourisheth.
For the wind passeth over it, and it is gone; and the place thereof shall know it no more.
But the mercy of the LORD is from everlasting to everlasting upon them that fear him, and his righteousness unto children's children;
To such as keep his covenant, and to those that remember his commandments to do them.
The LORD hath prepared his throne in the heavens; and his kingdom ruleth over all.
Bless the LORD, ye his angels, that excel in strength, that do his commandments, hearkening unto the voice of his word.
Bless ye the LORD, all ye his hosts; ye ministers of his, that do his pleasure.
Bless the LORD, all his works in all places of his dominion: bless the LORD, O my soul.
