'Give Thanks' in the Bible

I continually give thanks to God on your behalf, for the favour he has bestowed on you thro' Jesus Christ;

if I am thankful for what I have, why should I chuse to be evil spoken of for that for which I give thanks?

otherwise if you should give thanks by the spirit in an unknown tongue, the hearer cannot but appear unlearned upon this occasion; how then can he say Amen to thy thanksgiving? since he does not conceive what you say.
