Atheist accusation of contradiction in the Bible

[TBC: Here is another Atheist accusation of contradiction in the Bible]:

ON THE HOLY LIFE-STYLE
"Go thy way, eat thy bread with joy, and drink thy wine with a merry heart..." -- Ecclesiastes:9:7Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God now accepteth thy works.
See All...

"...they that rejoice, as though they rejoiced not..." -- 1 Corinthians:7:30And they that weep, as though they wept not; and they that rejoice, as though they rejoiced not; and they that buy, as though they possessed not;
See All...

[TBC: This really should be an embarrassment to point this out as a contradiction. The passage from Ecclesiastes is talking about "behavior" and the passage in 1 Corinthians addresses "attitude." That is evident from the context and from the words used in each passage had the atheist been looking for meaning rather than loopholes.]
