for let not that man think that he shall receive anything from the Lord;
for let not that man think that he shall receive anything from the Lord;
James 1:5 But if any one of you lack wisdom, let him ask of God, who gives to all freely and reproaches not, and it shall be given to him:
James 1:6 but let him ask in faith, nothing doubting. For he that doubts is like a wave of the sea driven by the wind and tossed about;
James 1:7 for let not that man think that he shall receive anything from the Lord;
James 1:8 [he is] a double-minded man, unstable in all his ways.
James 1:9 But let the brother of low degree glory in his elevation,
The verse centers on "think", "shall", "receive", "anything", and "lord". It is saying that the verse draws attention to "think" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "but let him ask in faith nothing..." into verse 8's "he is a double-minded man unstable in...", so "think" and "shall" belong inside that flow. In James context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "think" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
