'Thanks' in the Bible

If I take my share [of food] with thankfulness, why am I accused because of something for which I give thanks?

and when He had given thanks, He broke it and said, “This is (represents) My body, which is [offered as a sacrifice] for you. Do this in [affectionate] remembrance of Me.”

Otherwise if you bless [and give thanks to God] in the spirit only, how will any outsider or someone who is not gifted [in spiritual matters] say the “Amen” [of agreement] to your thanksgiving, since he does not know what you are saying?

You are giving thanks well enough [in a way that God is glorified], but the other person [who does not understand you] is not edified [and spiritually strengthened since he cannot join in your thanksgiving].

but thanks be to God, who gives us the victory [as conquerors] through our Lord Jesus Christ.
